Precision Machined Components for Hydraulic and Fluid Power Systems
ORRCO produces precision machined hydraulic components for fluid power OEMs and manufacturers, with over 80 years of experience holding the tight tolerances that hydraulic applications demand.
Hydraulic and fluid power applications leave no room for dimensional error. Leaks, pressure failures, and flow inconsistencies often trace back to machined components that don’t meet spec. ORRCO has been producing precision hydraulic components for over 80 years, with the tight-tolerance capability and process control that fluid power applications demand.
From valve bodies and spools to fittings, manifolds, and cylinder components, ORRCO machines the full range of precision machined hydraulic components that fluid power systems depend on. We work directly with OEM engineers and procurement teams to ensure every part meets your exact specifications — and we back every order with our ISO 9001:2015 certified quality system.
Hydraulic Components We Machine
- Hydraulic valve bodies and housings
- Valve spools and sleeves
- Manifold blocks
- Cylinder end caps and pistons
- Hydraulic fittings and adapters
- Flow control orifices and restrictors
- Pump components
- Cartridge valve components
- Custom connectors and ports
Tight Tolerances for Leak-Free Performance
Many hydraulic components require bore diameters, land widths, and surface finishes that must be held to extremely tight tolerances to ensure proper sealing and controlled flow. ORRCO routinely machines components to tolerances of ±0.0001 inches and achieves the surface finish specifications required for hydraulic sealing surfaces.
Our multi-axis CNC mill-turn capability is particularly well-suited to hydraulic valve components that require precise bores, cross-drilled ports, and complex external geometry — all produced complete in a single setup.
Hydraulic systems operate under extreme pressure — in many applications exceeding 3,000 PSI. At these pressures, a bore diameter that’s even a few tenths out of spec can mean the difference between a system that performs reliably for years and one that leaks or fails prematurely. ORRCO’s machinists understand these stakes and bring the process discipline to consistently hit the tolerances your hydraulic components require, run after run.
Materials for Hydraulic Applications
- Brass — widely used for fittings, adapters, and valve bodies
- Steel and Alloy Steel — high-pressure applications and cylinder components
- Stainless Steel — corrosion-resistant fluid handling components
- Aluminum — lightweight manifolds and housings
High-Volume Production for Fluid Power OEMs
Hydraulic component manufacturers and fluid power OEMs often require large quantities of identical parts with consistent quality. ORRCO’s multi-spindle screw machining capability is designed for exactly this kind of high-volume, tight-tolerance production — delivering thousands of precision components per run with the repeatability your assembly line depends on.
Quality Control for Hydraulic Parts
Every hydraulic component we produce goes through dimensional inspection before shipment. Our ISO 9001:2015 certified quality system ensures traceability from raw material to finished part. Our in-house ultrasonic cleaning service ensures components arrive free of chips, coolant residue, and particulate.
Medical-grade cleanliness isn’t just for medical parts — hydraulic systems are equally sensitive to contamination. Even small particles can cause valve sticking, seal damage, and premature wear. ORRCO’s ultrasonic cleaning process ensures every component arrives ready for immediate assembly into your system.
Why Hydraulic Manufacturers Choose ORRCO
When sourcing precision machined hydraulic components, you need a supplier who understands both the machining process and the consequences of getting it wrong. At ORRCO we’ve been producing hydraulic parts for decades — valve bodies, spools, fittings, and custom fluid control components for OEMs across the United States and internationally.
Our ISO 9001:2015 certified facility in Greensburg, PA combines multi-spindle screw machining for high-volume runs with CNC mill-turn capability for complex, multi-feature parts. Whether you need thousands of identical fittings or a complex valve body with tight bore tolerances, ORRCO has the equipment and experience to deliver.
