Seamless Compatibility: Crimp hose fittings are designed for easy connection with 1/4" I.D. hydraulic hoses. These fittings have a 1/4" NPTF external thread end, ideal for fluid power systems and hydraulic applications. Versatile Application: Hydraulic fittings are made of premium carbon steel, can endure temperatures from -65°F to 500°F, suitable for use with industrial fluids, including petroleum-based fluids, gasoline, fuel, and lubricating oils. Secure Connections: 1/4" NPTF male fittings have a permanent crimp design, requiring a crimping machine to connect a hose and fitting securely to prevent leaks. The straight shape of the fitting further improves connection stability. Essential for Hydraulic Systems: Hydraulic end repair kits connect hoses to various components in a hydraulic system, compatible with Weatherhead/Eaton/Dayco U-Series wire braid hoses. Good Processing: All important surfaces are well machined including the threads with nice plastic caps, the threads are well machined with no burrs. 12Pack 1/4" Hose Hydraulic Fittings
