Is the MSL threaded coupling with galvanized hose end, brass nut & aluminum clamp EN 14420-3 (DIN 2817) suitable for continuous use at 25 bar in LPG installations?

Yes. The MSL threaded coupling with galvanized hose end, brass nut & aluminum clamp EN 14420-3 (DIN 2817) is suitable for continuous use at 25 bar in LPG installations. It is manufactured to EN 14420-3 (DIN 2817) standards, uses a galvanized carbon steel fitting for corrosion and wear resistance, a brass nut with internal thread for a secure seal, and an aluminum shell clamp for durable hose retention. The product specification states a working pressure of up to 25 bar, indicating it is designed to deliver consistent, long-term performance at that pressure in professional liquefied gas systems.

Can the MSL threaded coupling with galvanized hose end, brass nut & aluminum clamp EN 14420-3 (DIN 2817) withstand pressure spikes above 25 bar in LPG systems?

MSL threaded coupling with galvanized hose end, brass nut & aluminum clamp EN 14420-3 (DIN 2817) is specified for a working pressure of up to 25 bar. It is designed and manufactured to meet EN 14420-3 (DIN 2817) standards using galvanized carbon steel fitting, brass nut and aluminum clamp, providing robust corrosion and mechanical resistance. However, it is not rated for sustained operation above 25 bar. Short-duration pressure spikes slightly above 25 bar may be tolerated depending on installation quality, system dynamics and applicable safety margins, but exceeding the certified working pressure risks seal or component failure and is not recommended. For systems subject to frequent or significant pressure spikes above 25 bar, select a coupling rated for the higher peak pressure and consult the manufacturer’s technical datasheet and a qualified engineer to verify suitability and safety.
