OUR SERVICES

Whether you need a single replacement for a metric utility tractor or a high-volume run of custom assemblies for a local manufacturing plant, SIG Hydraulics builds to your exact specifications. Our primary facility in Salem, Ohio, is equipped for both fast walk-in walk-out repairs and scheduled contract production. We don't just sell bulk hose. We build engineered assemblies designed to survive high vibration, extreme pressure cycles, and rough environments. Our fabrication range covers standard hose inside diameters from 3/16" all the way up to 2" for high-flow return and suction lines. We stock a wide array of hose styles. This includes standard SAE 100R1 and 100R2 wire-braided hoses for medium-pressure systems. We also stock 4-wire and 6-wire spiral-reinforced hoses (SAE 100R12, 100R13, and 100R15) designed for constant working pressures up to 6000 PSI. For special applications, we stock thermoplastic hoses, non-conductive lines for utility trucks, and suction hoses with steel wire coils that won't collapse under vacuum. The secret to a reliable hose is matching the fitting exactly. A thread that looks close but is off by a fraction of a millimeter will strip or leak under load. Our Salem shop is equipped with precision thread identification tools. We measure pitch, seat angles, and diameter. We stock standard American threads: JIC 37-degree flare, O-Ring Face Seal (ORFS), National Pipe Thread (NPTF), and SAE O-Ring Boss (ORB). We also carry a full inventory of metric and international fittings. This includes British Standard Pipe Parallel (BSPP), British Standard Pipe Tapered (BSPT), and Japanese Industrial Standard (JIS). We stock German DIN light and heavy series metric fittings. If your machine was built in Europe or Asia, we can match the thread. We use professional-grade shop tooling. Our primary shop press is a Uniflex HM465 400-ton industrial crimper. This machine delivers the massive force needed to crimp multi-spiral hoses up to 2 inches and large-bore industrial lines. The Uniflex crimper uses a split-die system that ensures even, 360-degree compression around the fitting collar. This prevents high-pressure leaks and collar slippage under extreme load cycles. Every crimp we make is measured with micrometer calipers and logged for quality control. Cleanliness is a priority, not an afterthought. Dirt is the number one killer of hydraulic systems. When we cut a hose, the abrasive wheel leaves rubber dust and metal particles inside the tube. If you install that hose raw, that debris goes directly to your pump, relief valves, and cylinders. It scores the polished steel surfaces, causing internal leaks and premature pump failure. At SIG Hydraulics, we clean every custom assembly we build. We use an Ultra-Clean foam projectile launcher. We blow a clean, dry foam plug through the hose before crimping the second end. After crimping, we seal both ends with heat-shrink plastic caps. This keeps road dust, moisture, and shop dirt out of the hose during transport and storage. To guarantee performance, we offer proof-testing. Our Salem shop houses a dedicated Uniflex P160 proof test bench. We test assemblies to full operational pressure or up to SAE J517 test specifications. The test bench is fully enclosed for safety. It can generate hydrostatic testing pressures up to 18,850 PSI. We provide physical or digital pressure test certificates when required. This is critical for municipal lifts, military logistics, and high-liability industrial systems. We also specialize in fitting angle alignment for complex dual-elbow assemblies. When building a hose with elbow fittings on both ends, the relative angle between the two elbows is critical. If the angle is off, the hose must be twisted during installation, which causes torsional stress and cuts its service life. We use specialized shop jigs to measure and set the exact angular displacement (in degrees) before crimping the collars. This ensures the hose seats naturally on your machine without twist. Our Salem facility also features a walk-in service counter. If you bring your damaged hose to our counter, our experienced technicians will identify, build, and clean a matching replacement while you wait. We understand that every minute of downtime is a loss. We maintain a huge inventory of adapter fittings and steel couplings to make sure we can build even rare or obsolete hose lines. You can grab a coffee, watch the fabrication process, and walk out with a completed, pressure-ready assembly in under fifteen minutes. We also offer custom labeling and asset management. We can mark each hose with custom aluminum tags or high-durability heat-shrink labels. We print part numbers, pressure ratings, installation dates, and QR codes. This makes replacement simple. If a labeled hose eventually wears out, you don't have to bring the machine or the dirty hose to our shop. Just call us with the part number on the tag. We will build a duplicate assembly and have it ready for pickup or dispatch a truck to install it. We understand that custom fabrication requires speed. If you walk into our Salem shop with a broken hose, our goal is to build your replacement in under fifteen minutes. If you have a bulk order, we schedule production to minimize lead times. We work directly with maintenance managers, plant engineers, and independent operators. No job is too small, and no custom run is too complex. We have the inventory, the machinery, and the experience to deliver exact, clean, and pressure-tested assemblies every time.

The cheapest hydraulic repair is the one you never had to make. When a hose blows on a machine in the middle of a job, you aren't just paying for a replacement hose. You're paying for a stranded crew, a stalled project, emergency dispatch fees, and clean-up costs for spilled oil. If you operate a fleet of excavators, skid steers, dump trucks, or farm machinery, waiting for lines to break is a losing strategy. Proactive maintenance keeps your equipment running and keeps your profit margins intact. SIG Hydraulics offers structured fleet service agreements and scheduled preventive maintenance inspections across Northeast Ohio and Western Pennsylvania. We don't just show up when things break. We partner with fleet managers and owner-operators to inspect, log, and service your hydraulic plumbing before a failure happens. Our technicians perform detailed on-site fleet audits. We inspect every machine from bucket to track. We look for the early signs of hydraulic hose wear. This includes checking for cracks in the outer rubber cover, exposed steel wire braiding, and bubbles or soft spots in the hose carcass. We inspect the crimp collars for corrosion and weeping fluid. A damp fitting is a sign that the inner tube is starting to separate from the coupling. It will blow eventually. A major focus of our inspections is hose routing. Many hoses fail because they were installed incorrectly during a previous rush repair. We look for twisted laylines. A hose that is twisted when tightened is under constant torsional stress, which reduces its pressure capacity by up to 70 percent. We check the bend radius of every line. If a hose is bent too tight near a fitting, the wire reinforcement fatiguing will cause a premature blowout. We also check for line interference. If a hose rubs against a frame rail, bracket, or another line, the outer cover will wear through, exposing the steel braid to moisture and rust. We correct these issues on-site. We install protective nylon sleeves, fire-resistant wraps, and plastic spiral guards. We add heavy-duty clamps and routing blocks to secure loose lines. We also conduct fluid analysis as part of our scheduled fleet service. We draw small oil samples from your machinery's hydraulic reservoirs using clean, diagnostic sampling bottles. These samples are analyzed in a certified laboratory to check for microscopic particle contamination (complying with ISO 4406 cleanliness standards) and elemental wear metals like copper, iron, and lead. This testing lets us identify pump, cylinder, or valve wear before it leads to a catastrophic system breakdown, letting you schedule repairs during planned maintenance windows instead of emergency shut-downs. In addition to physical wear, we perform thermal inspections of active hydraulic systems. Our technicians use infrared thermal cameras to scan hoses, pumps, and manifold blocks while the machine is operating under load. Heat anomalies indicate internal restrictions or bypassing, such as a valve spool that is not seating correctly or an inner hose lining that has collapsed and is choking flow. Spotting these thermal hot spots helps us locate hidden system faults before they cause a blowout or burn out a hydrostatic pump. Each machine we inspect gets a digital log. We tag every critical hose with a unique part number and installation date. This creates a clear maintenance history for your fleet. We can identify which hoses are approaching the end of their operational life based on service hours and exposure. We replace these worn soft-lines in a controlled environment, preventing unexpected field failures. Our preventive maintenance service also includes basic fluid health checks. We check hydraulic fluid levels and inspect the reservoir seals. We look for signs of oil contamination, such as cloudy or milky fluid, which indicates water intrusion, or dark, burnt oil, which indicates overheating. We inspect the return line filters and suction strainers. We make sure your oil stays clean. Clean oil extends the life of your expensive pumps, control valves, and cylinders. Fleet agreement clients receive priority status. When an emergency does happen, your machines are moved to the front of our dispatch queue. We already have your fleet data on file. We know what hoses, fittings, and routing configurations your machines use. This makes our emergency response even faster. Investing in preventive maintenance is about controlling your costs. You reduce the number of emergency service calls, eliminate environmental cleanup liabilities from oil spills, and extend the lifespan of your heavy machinery. We keep your fleet Plumbed Right. That means your operators stay productive, your projects stay on schedule, and you keep more money in your pocket. Contact SIG Hydraulics to discuss a custom fleet agreement for your operation. We work with your schedule. We know you can't shut down your fleet during peak operational hours. We schedule preventive inspections and maintenance during planned downtime. This includes evenings, weekends, or seasonal windows. For paving and construction crews, we perform complete fleet inspections during the late winter and early spring before the paving season starts. For agricultural operators, we service combines, tractors, and grain carts before planting and harvest rushes. For municipal departments, we inspect snowplow lifts and salt spreader lines in the autumn before the first freeze.

High-volume manufacturing and government procurement require a hydraulic partner who understands logistics, compliance, and heavy tooling. SIG Hydraulics is a certified Service-Disabled Veteran-Owned Small Business (SDVOSB). We combine federal contractor eligibility with the heavy industrial capabilities required for bulk OEM production, large-bore hose assembly, and municipal fleet support. Our production workflows are designed to deliver zero-defect runs on time, every time. Our Salem, Ohio facility is set up for high-capacity contract manufacturing. Unlike standard mobile trucks that build one hose at a time, our shop utilizes automated production machinery to handle large orders efficiently. We use computer-controlled hose cutters that deliver clean, square cuts across multi-wire spiral hoses. This ensures the hose seats perfectly inside the fitting collar before crimping, which is critical for pressure integrity. We house heavy-duty crimping tooling capable of handling large-bore hoses up to 8 inches in diameter. Our primary shop press is the Uniflex HM465. Delivering 400 tons of crimping force, this machine handles large-diameter industrial suction lines, heavy oilfield supply lines, and high-pressure military transport hoses. The Uniflex split-die design ensures precise, radial compression. This eliminates the risk of oval crimps or uneven collar squeeze, which can cause premature hose failure. We operate under strict quality management protocols. Every single OEM and government run follows a documented Quality Assurance (QA) pipeline. We build to print, verifying every dimension, fitting angle, and hose specification against your engineering drawings. We use digital caliper measurement systems to check crimp diameters on every batch. All assemblies we build comply with SAE J517 standards. We do not guess at quality. We prove it. Our Salem shop is equipped with the Uniflex P160 proof test bench. This test enclosure allows us to subject completed assemblies to hydrostatic testing up to 18,850 PSI. We can perform 100% proof-testing on production runs. This ensures that every hose shipped meets the required safety factor and operating pressure. We generate custom test reports and pressure charts for each assembly. These logs are stored digitally and can be supplied as physical test certificates with your order. Our quality assurance protocols also incorporate raw material traceability. We track the heat numbers and mill test reports (MTR) for all steel couplings and flange fittings used in our production runs. This means we can trace every raw metal batch back to the domestic forge. This level of tracking is mandatory for military contracts, critical infrastructure builds, and high-liability industrial machinery. We provide full material certifications with every shipment to ensure compliance with strict procurement guidelines. To support government and military contractors, we streamline the procurement process. We accept Government Purchase Cards (GPC) and are registered in the System for Award Management (SAM) with active UEI (Unique Entity Identifier) and CAGE code profiles. We can supply complete documentation for Buy American Act compliance. We also provide full SDS data sheets and material safety certifications. We work regularly with municipal procurement officers, state agencies, and military logistics hubs. To simplify parts tracking and logistics, we offer digital traceability. We label every assembly with a durable QR code tag. When scanned, this code links directly to the digital build record, showing the hose model, fitting types, crimp measurements, test pressure, and fabrication date. This makes reordering simple for fleet operators and OEM warehouse managers. If a hose needs replacement in the field, your logistics team scans the QR code to pull the exact bill of materials instantly. We offer customized supply chain integration for local OEM manufacturers. We can build and stock pre-packaged hose kits for your assembly lines. Instead of your workers pulling individual hoses, fittings, and clamps from separate bins, we deliver a single, sealed kit containing every pre-fabricated, cleaned, and capped line required for a specific machine build. This reduces your assembly time, minimizes inventory tracking costs, and eliminates line-stoppages. We protect your systems from contamination. All bulk production assemblies go through our cleaning process. We use dry foam projectiles to sweep out internal debris, and we seal the fittings with heavy-duty heat-shrink caps before packing. We ship our assemblies in protective, labeled crates to prevent damage during transit. SIG Hydraulics combines the agility of a veteran-owned business with the tooling and quality systems of a national manufacturer. Whether you are bidding a municipal utility contract, sourcing bulk assemblies for an agricultural machinery line, or procuring high-pressure lines for defense logistics, we have the capability to deliver. Contact our Salem office to review your engineering drawings and request a production quote. As a certified SDVOSB, SIG Hydraulics is fully registered in the System for Award Management (SAM) under NAICS codes including 332912 (Fluid Power Valve and Hose Fitting Manufacturing) and 811310 (Commercial and Industrial Machinery and Equipment Repair and Maintenance). We understand the administrative requirements of government contracting. We provide complete documentation, including COTS (Commercial Off-The-Shelf) compliance, Buy American Act certification, and detailed material safety data sheets. We work closely with municipal utility departments, county highway engineers, military logistics bases, and state agencies. We source all our steel fittings and hose stocks from domestic suppliers to meet strict Buy American requirements. We don't cut corners on certification. We keep your project on schedule.
