How to Choose the Right Hose Product

Match hose series, end fitting style, and assembly method (crimp vs. field-attachable) to the system pressure and environment.

• Match Hose Series to the System’s Pressure and Fluid SAE hose ratings define the application: 100R1AT single wire braid is rated for moderate hydraulic pressures in mobile equipment and general industrial circuits. 100R2AT double wire braid handles higher pressures and higher-impulse cycles. Spiral-wound hose is specified for the highest pressures and most demanding impulse environments. Air brake and fuel hose must meet their respective SAE standards (J1402/FMVSS106 and J1527) — these are not interchangeable with hydraulic hose, regardless of bore size or appearance. Confirm the hose series matches both the system pressure and the fluid being conveyed before cutting.
• Select the End Fitting Style to Match the Port The end fitting must match the port connection standard at both ends of the assembly — JIC 37° flare, ORFS, NPT, or air brake. JIC fittings seal on the flare cone and are common in existing mobile equipment and industrial machinery. ORFS provides a more leak-resistant seal at high pressures and is the preferred standard for new designs. NPT is common at low-pressure ports and fluid reservoirs. Never substitute fitting styles — a JIC fitting on an ORFS port creates a leaking, non-sealing assembly regardless of how tight the nut is torqued.
• Choose Crimp Over Field-Attachable for Permanent Assemblies Crimped (swaged) hose assemblies are the professional standard for hydraulic circuits — the ferrule is permanently deformed onto the hose, creating a connection whose pull-out strength and pressure rating are certified by the manufacturer when made with matched hose and fitting. Field-attachable (reusable) fittings are appropriate for field repairs when a crimper is unavailable, but should be replaced with a crimped assembly at the next service opportunity for permanent installations. Never use a field-attachable fitting at pressures above its rated working pressure.
