Hydraulic Fitting Standards We Carry

JIC (37° Flare) — The most common fitting standard in North American hydraulic systems. Available in 37° flare male and female configurations in sizes from -4 (1/4") to -32 (2"). ORFS (O-Ring Face Seal) — Zero-leak performance for high-vibration and high-pressure applications up to 6,000 PSI. SAE O-Ring Boss — Port connections for valves, pumps, and cylinders. NPT/NPTF — Tapered pipe thread fittings for lower-pressure connections. BSP — British Standard Pipe for imported and European equipment. Metric DIN — DIN 2353 bite-type fittings for European hydraulic systems.

Quick Disconnects & Live Swivels

Our hydraulic quick disconnects (flat-face and poppet-style) allow tool and attachment changes without fluid spillage. Live swivels prevent hose twist and fatigue on rotating and oscillating hydraulic lines.
