Does End 90Â° ORFS INTERLOCK GW UNF, carbon steel, fit hoses 4SH, R13, and R15 with flat-sealing UNF internal thread?

Yes. End 90Â° ORFS INTERLOCK GW UNF, carbon steel is designed to fit hoses 4SH, R13, and R15 and features an internal UNF thread with flat (ORFS) face sealing. The description matches: 90Â° ORFS INTERLOCK fitting, internal UNF thread, flat sealing, for hose types 4SH, R13, and R15, carbon steel (galvanized). Ensure hose assembly and crimping follow manufacturer specs and that the UNF thread size matches your mating connector.

Can End 90Â° ORFS INTERLOCK GW UNF, carbon steel, be used with ORFS-compatible hydraulic hoses besides 4SH, R13, and R15?

End 90Â° ORFS INTERLOCK GW UNF, carbon steel is specified for hose types 4SH, R13, and R15. Using it with other ORFS-compatible hoses is possible only if those hoses match the same dimensional (inside diameter, reinforcement layers, crimp profile) and pressure/temperature ratings required by the fitting and the interlock ferrule design. Deviations can cause improper crimping, leakage, or failure despite ORFS face-seal compatibility. Before substituting, verify: hose outer diameter and ferrule/crimp geometry compatibility, working pressure and safety factor, temperature and media compatibility with carbon steel plating, and consult manufacturer crimp specs or perform qualification testing. If in doubt, use hoses explicitly listed by the fitting maker.

Is End 90Â° ORFS INTERLOCK GW UNF, carbon steel, compatible with metric-size UNF-threaded hose ends?

Possibly not reliablyâcompatibility depends on thread form and tolerance, not just nominal UNF size. Explanation: End 90Â° ORFS INTERLOCK GW UNF, carbon steel is an ORFS (O-Ring Face Seal) interlock style fitting that incorporates an internal UNF thread to accept a male threaded component. ORFS systems seal on a flat face with an Oâring, while UNF is a Unified Fine external/internal thread series specified in inches. Metric-size UNFâthreaded hose ends (if by that you mean hose ends made to metric dimensions but using a UNF thread profile) create two potential issues: 1. Thread profile & pitch: True UNF threads use imperial pitch (threads per inch). Metric threads use millimeter pitch and different flank angles. If the hose end is metric (Mâseries) it will not match a UNF internal thread at all. If the hose end is called âmetric-size UNF-threadedâ but actually machined to UNF dimensions, it must precisely match the UNF nominal size and tolerance for proper engagement. 2. Sealing method: ORFS fittings rely on a flat face + Oâring for the pressure seal; the threaded engagement only provides mechanical retention. If the mating hose end is a UNF male designed to seat an ORFS flat face with an Oâring, it can be compatible provided the male geometry (flat face surface for Oâring, correct shoulder position) and UNF thread size/pitch match the End 90Â° INTERLOCKâs internal UNF. If the male hose end is a conventional UNF hose fitting that expects thread metalâtoâmetal or uses different sealing geometry, it will not seal properly. Conclusion: If the hose end is truly UNF (imperial) with the correct thread size, pitch and ORFSâcompatible face for the Oâring, End 90Â° ORFS INTERLOCK GW UNF, carbon steel will be compatible. If the hose end is metricâthreaded or differs in thread form/pitch or lacks the proper ORFS sealing face, it will not be compatible. Verify exact thread spec (UNF size & class) and face geometry before mating.
