Hydraulic Fitting Selection — Quick Reference
Hydraulic fittings CONNECT HOSE + TUBE + PIPE to hydraulic components — cylinders + valves + pumps + manifolds. CRITICAL high-pressure connections — sealing + pressure rating + thread form must match exactly.
| Hydraulic Fitting Type | Best For |
|---|---|
| JIC 37° Flare | Flare seal — US-origin standard |
| ORB (O-Ring Boss) | Premium O-ring sealed |
| ORFS (O-Ring Face Seal) | Premium flat-face O-ring |
| BSP Parallel + Bonded Seal (Dowty) | AU + EU standard — see dowty washer guide |
| BSP Tapered (BSPT) | Lower pressure threaded |
| NPT (American) | US-origin equipment |
| DIN 24° Cone | EU standard |
| Compression Fitting (Tube) | Tube termination |
| Hose End Crimp Fitting | Hydraulic hose assembly |
| Quick-Disconnect Coupling | Frequent connect/disconnect |
Critical: NEVER MIX thread forms (JIC vs BSP vs NPT vs DIN — different angles). Match PRESSURE RATING + media + temperature. Use proper crimp tooling for hose end. Brands: Dixon, Parker. Companion: hydraulics, hose + tube connectors, pipe fittings.
Hydraulic Fittings for Hose, Tube and Component Connections
Hydraulic fittings connect hose, tube, and pipe to hydraulic components including cylinders, valves, pumps, motors, and manifolds. Selecting the correct fitting involves matching the thread form and size on both the fitting and the port, verifying the fitting's pressure rating against the system's working and peak pressure, and choosing an appropriate material and sealing method for the fluid and environment. AIMS stocks a comprehensive range of hydraulic fittings in the common thread standards used in Australian industrial and mobile equipment applications.
Thread Standards and Port Types
BSP (British Standard Pipe) parallel thread with bonded seal is the most common port type on hydraulic components manufactured for the Australian and European markets. BSP parallel (BSPP, G thread) fittings seal on a bonded seal (Dowty washer) or O-ring, making them reliable and reusable. BSPT tapered thread fittings seal on the thread taper and are common in older equipment and plumbing connections. JIC 37-degree flare fittings are standard on much North American and agricultural equipment. O-ring face seal (ORFS) fittings are increasingly specified in new hydraulic system designs for their superior leak-free performance under vibration and pressure impulse conditions.
Adapters and Conversions
Hydraulic adapter fittings allow connections between different port types, thread sizes, and configurations — for example, converting a BSPP port to accept a JIC hose end, or reducing a larger bore port to accept a smaller tube. AIMS stocks a broad range of male-to-male, male-to-female, and swivel adapters in common BSP, JIC, metric, and ORFS combinations. Banjo fittings allow 90-degree connections in tight spaces where a conventional straight or elbow fitting would not fit, and are widely used in fuel injection, lubrication, and hydraulic control circuits on compact machinery.
Hose End Fittings
Hose end fittings are crimped or swaged onto hydraulic hose to provide the threaded end connection. These fittings are engineered as a matched system with the hose — the fitting's ferrule dimensions, crimp die size, and crimp diameter are all specific to the hose and fitting combination. Never interchange hose end fittings between different hose brands or attempt to field-crimp fittings without the correct crimp tooling and dimensional data, as an incorrect crimp can result in hose blow-off at working pressure — a serious safety hazard in hydraulic systems.
