Female threaded coupling with smooth tail with lock for shell clamp, AISI 316 steel, brass nut, type MSL

Q: Can the Female threaded coupling with smooth tail with lock for shell clamp, AISI 316 steel, brass nut, type MSL be used with crimping sleeves instead of shell clamps?

Yes . the Female threaded coupling with smooth tail with lock for shell clamp, AISI 316 steel, brass nut, type MSL can be used with crimping sleeves instead of shell clamps. The Internal BSP threaded connector with a rotating nut and hose end, type MSL is designed for mounting to rubber hoses and certain industrial plastic hoses and is fastened using shell clamps EN 14420-3 / DIN 2817 (only clamps RS 636... and RS-637...). The product description also states they can be clamped with appropriate crimping sleeves. Working pressure (25 bar), materials (AISI 316 hose end, brass nut), sealing (flat gasket with PTFE) and operating temperature (-20Â°C to +65Â°C) remain the same; ensure you use compatible crimping sleeves sized and rated for the hose type and working pressure.

Q: Is the Female threaded coupling with smooth tail with lock for shell clamp, AISI 316 steel, brass nut, type MSL suitable for hoses beyond rubber and specified plastics?

No. The Female threaded coupling with smooth tail with lock for shell clamp, AISI 316 steel, brass nut, type MSL Format is specified for mounting to rubber hoses and certain industrial plastic hoses only. It is fastened using shell clamps EN 14420-3 / DIN 2817 (RS 636... and RS-637...) or suitable crimping sleeves, rated to 25 bar, with AISI 316 hose end, brass nut, PTFE gasket and operating range â20Â°C to +65Â°C. Use on other hose materials is not covered by the specification and may compromise sealing, clamp compatibility and safety. Consult manufacturer for approval if you intend to use different hose types.

Q: Can the Female threaded coupling with smooth tail with lock for shell clamp, AISI 316 steel, brass nut, type MSL withstand temperatures below -20Â°C?

Yes. Female threaded coupling with smooth tail with lock for shell clamp, AISI 316 steel, brass nut, type MSL is rated for operation down to â20Â°C according to the specification (Operating temperature: from â20Â°C to +65Â°C per ENâ14420). Temperatures slightly below â20Â°C may risk reduced material ductility, gasket hardening or seal failure (standard PTFE gasket is more resistant than elastomers), so use below â20Â°C is not covered by the stated rating and is not recommended without manufacturer confirmation or testing.
