Is the Full-flow quick coupling socket with hose end, NITTO KOHKI TSP CUPLA, brass suitable for steam at 150Â°C with Viton seals?

Yes. Full-flow quick coupling socket with hose end, NITTO KOHKI TSP CUPLA, brass with Viton seals is rated for steam service at temperatures up to +180Â°C (Viton operating range) per the spec. Ensure your steam pressure does not exceed the couplingâs working pressure for the hose size in use (50 bar for 1/8"â3/8", 30 bar for 1/2"â1", 20 bar for 1Â¼"â1Â½", 15 bar for 2"). Also verify compatibility with your specific steam conditions (wet/dry, condensate, thermal cycling) and applicable safety standards; consider pressure/temperature margins and periodic inspection.

Can the Full-flow quick coupling socket with hose end, NITTO KOHKI TSP CUPLA, brass handle aggressive chemicals at 80Â°C with NBR seals?

Yes - the Full-flow quick coupling socket with hose end, NITTO KOHKI TSP CUPLA, brass can handle aggressive chemicals at 80Â°C only if fitted with Viton seals. NBR seals are rated to +80Â°C but are generally not suitable for aggressive chemicals; exposure at the upper temperature limit risks rapid deterioration and failure. For aggressive chemicals and temperatures up to 80Â°C, choose the Viton seal option (rated to +180Â°C) to ensure chemical compatibility and reliable service.

Can Full-flow quick coupling socket with hose end, NITTO KOHKI TSP CUPLA, brass be used for hydraulic oil at 60Â°C with NBR seals?

Yes. Full-flow quick coupling socket with hose end, NITTO KOHKI TSP CUPLA, brass can be used for hydraulic oil at 60Â°C with NBR seals. The product specification lists hydraulic oils among intended fluids, and the NBR seal operating range is â20Â°C to +80Â°C, so 60Â°C is within the allowable temperature. Also check that system working pressure does not exceed the couplingâs rated pressure for the chosen size (50â15 bar depending on size). Verify chemical compatibility of the specific hydraulic oil formulation with NBR and confirm installation and maintenance practices to ensure long-term sealing performance.
