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

Yes. The End 90° ORFS Interlock Female UNF, Carbon Steel is compatible with 4SH, R13, and R15 hoses and is suitable for high-pressure hydraulic systems. It features an internal UNF thread with a flat sealing system for leak-free connections under extreme pressure, is manufactured from robust carbon steel with high-quality galvanization for corrosion and wear resistance, and is engineered for secure, durable performance in demanding heavy-duty applications.

Can the End 90° ORFS Interlock Female UNF, Carbon Steel fitting be used with aggressive fluids or require special seals for chemical compatibility?

The End 90° ORFS Interlock Female UNF, Carbon Steel is designed for heavy-duty hydraulic use with a flat sealing system and carbon steel construction with galvanization, which gives good general resistance to corrosion and mechanical wear. However, carbon steel and standard seals used with ORFS fittings are not universally compatible with aggressive chemicals. For aggressive fluids (strong acids, alkalis, solvents, or specialty chemicals), you should verify chemical compatibility of both the metal and the seal material. Recommendations: - Confirm the specific fluid chemistry and concentration. - Use compatible seal materials (e.g., PTFE, FKM/Viton, EPDM, or others chosen for the specific chemical) rather than standard NBR if needed. - For highly corrosive fluids, consider alternative materials (stainless steel or specialty alloys) or protective coatings. - Consult the fitting and seal manufacturers’ chemical compatibility charts and perform compatibility testing where safety-critical. In short: the End 90° ORFS Interlock Female UNF, Carbon Steel may be suitable for many hydraulic fluids, but aggressive fluids often require special seals and possibly different base materials for chemical compatibility.
