Is the INTERLOCK Straight End GW BSP, Carbon Steel compatible with hose types 4SH, R13, and R15?

Yes — the INTERLOCK Straight End GW BSP, Carbon Steel is compatible with hose types 4SH, R13, and R15. The fitting features a 60° cone and integrated O‑ring to ensure a secure, leak‑free connection under high pressure. Made from carbon steel with a galvanized finish, it offers high corrosion and wear resistance for heavy‑duty industrial and mobile hydraulic systems. Its precise design enables easy installation, optimal sealing, and long‑term reliability with these hose types.

Does the INTERLOCK Straight End GW BSP, Carbon Steel require a specific O-ring material for high-temperature hydraulic systems?

INTERLOCK Straight End GW BSP, Carbon Steel does not explicitly mandate a single O‑ring material in the provided description, but because it’s specified for demanding, high‑temperature hydraulic applications with a 60° cone and integrated O‑ring, you should choose an O‑ring material rated for the system’s maximum temperature and compatible with the hydraulic fluid. Common high‑temperature choices include: - FFKM (perfluoroelastomer): excellent high‑temperature and chemical resistance for extreme conditions. - FKM (Viton): good high‑temperature performance and broad fluid compatibility for many hydraulic oils. - PTFE (as a backup/seal element) or metal‑energized seals for very high temperatures or abrasive service. Avoid standard NBR (Buna‑N) in high‑temperature applications as its thermal limits are lower. Verify the exact operating temperature, pressure, and fluid chemistry, and consult seal manufacturer data to ensure compatibility with INTERLOCK Straight End GW BSP, Carbon Steel and the system’s demands.
