Is the 90° JIC Interlock Female UNF End, Carbon Steel compatible with 4SH, R13, and R15 hoses for high-pressure hydraulic systems?

Yes. The 90° JIC Interlock Female UNF End, Carbon Steel is compatible with 4SH, R13, and R15 hoses for high-pressure hydraulic systems. Its 74° cone with integrated O-ring provides a secure, leak-free seal designed for extreme pressures, and the interlock design ensures a reliable mechanical connection. Manufactured from high-quality carbon steel with a galvanized finish, it offers enhanced corrosion and wear resistance for long service life, easy installation, and reduced maintenance—making it suitable for demanding industrial hydraulic applications.

Does the 90° JIC Interlock Female UNF End, Carbon Steel require a specific O-ring material for optimal sealing in extreme-temperature hydraulic systems?

90° JIC Interlock Female UNF End, Carbon Steel Format: Yes. The fitting features an integrated O-ring intended to enhance sealing under extreme pressure and temperature, but optimal O-ring performance depends on the specific operating temperature range and fluid compatibility. For extreme-temperature hydraulic systems choose an O-ring material rated for both the high and low temperatures encountered and compatible with the hydraulic fluid used. Common recommendations: - Fluoroelastomer (FKM/Viton) for high-temperature resistance and good chemical compatibility with many hydraulic oils. - Hydrogenated Nitrile (HNBR) for a broader temperature range and excellent resistance to oils and abrasion. - Perfluoroelastomer (FFKM) for the most extreme temperatures and aggressive fluids (highest cost). - PTFE (or PTFE-lined) may be used where chemical inertness and very high temperatures are required, though it has different sealing characteristics. Confirm the system’s min/max temperatures, fluid type, pressure cycles and any regulatory requirements, then select an O-ring compound rated accordingly to ensure reliable sealing with the 90° JIC Interlock Female UNF End, Carbon Steel Format.
