Is the Flange end 90Â° INTERLOCK SAE 3000, carbon steel compatible with hose types 4SH, R13, and R15 using an O-ring seal or gasket in the flange groove?

Yes. Flange end 90Â° INTERLOCK SAE 3000, carbon steel is compatible with hose types 4SH, R13, and R15 when an O-ring seal or other gasket is installed in the flange groove. These hoses are designed for high-pressure hydraulic applications and use SAE 3000 (3,000 psi) interlock flanges; the flange groove is intended to accept an O-ring or gasket to ensure a pressure-tight seal. Carbon steel, galvanized flange material is suitable for these hose types provided correct gasket/O-ring material (e.g., nitrile, FKM/Viton, or other elastomers rated for the system fluid and temperature) and proper flange bolt torque are used. Ensure mating flange faces, groove dimensions, and O-ring/gasket size match SAE 3000 specifications and follow manufacturer installation and pressure ratings for safe operation.

Can Flange end 90Â° INTERLOCK SAE 3000, carbon steel with an O-ring/gasket in the groove meet pressure and sealing requirements for hoses 4SH, R13, and R15?

Flange end 90Â° INTERLOCK SAE 3000, carbon steel with an O-ring/gasket in the flange groove can meet pressure and sealing requirements for hoses 4SH, R13, and R15 provided conditions are met: flange, Oâring/gasket and hose are all rated for SAE 3000 psi service; hose fittings and hose interior/exterior dimensions match the flange bore and groove; selected Oâring/gasket material is compatible with the hydraulic fluid, temperature range and pressure cycling; proper assembly torque and surface finish are used; galvanization does not impair sealing surfaces. If any componentâs rating, material compatibility, or dimensional fit is insufficient, the assembly will not reliably seal. Recommend verifying manufacturer specs and performing pressure testing to confirm compliance.

Can Flange end 90Â° INTERLOCK SAE 3000, carbon steel with an O-ring/gasket in the groove be used for 4SH, R13, and R15 hoses?

Yes. Flange end 90Â° INTERLOCK SAE 3000, carbon steel with an O-ring/gasket in the flange groove can be used for hose types 4SH, R13, and R15, with the following conditions met: - Compatibility: 4SH, R13, and R15 are high-pressure, multi-wire braided hydraulic hoses commonly ending with SAE 3000 (3000 psi) flange terminations. Flange end 90Â° INTERLOCK SAE 3000, carbon steel is designed for this pressure class and hose family, so it is mechanically compatible when correctly assembled. - Seal: The presence of an O-ring or other gasket in the flange groove provides the required face seal for hydraulic fluids. Use the correct O-ring material (e.g., NBR, FKM/Viton, or other elastomer compatible with the hydraulic fluid, temperature, and pressure) and correct size specified for SAE 3000 flanges. - Assembly: Proper crimping or swaging of the fitting to the specific hose construction (4SH, R13, R15) is essential. Use tooling and dies matched to the hose and flange model, follow manufacturer crimp specs, and ensure correct insertion depth and ferrule orientation for the interlock design. - Material and corrosion protection: Carbon steel, galvanized, is typical and acceptable for many hydraulic applications. Verify galvanization and any coating are compatible with the operating environment (e.g., salt spray, chemical exposure). Consider stainless options if corrosion risk is high. - Pressure/temperature ratings: Confirm the assembled hose assembly (hose + Flange end 90Â° INTERLOCK SAE 3000, carbon steel + O-ring) meets the systemâs maximum working pressure and temperature for the chosen hose type and O-ring material. - Standards and testing: After assembly, perform pressure testing per applicable standards (SAE, ISO, or company spec) to confirm leak-free performance. If these conditions are satisfied. correct O-ring material, proper assembly/crimping for 4SH/R13/R15, and verification of ratings. Flange end 90Â° INTERLOCK SAE 3000, carbon steel with an O-ring/gasket in the groove is suitable for use with 4SH, R13, and R15 hoses.
