Is the CEJN 232 Quick Connect Screw Plug with NPT Valve, Carbon Steel safe to connect or disconnect under residual system pressure?

Yes. The CEJN 232 Quick Connect Screw Plug with NPT Valve, Carbon Steel is designed to be connected and disconnected safely even when residual pressure remains in the hydraulic system. Engineered for extremely high pressures (working pressure 700 bar, burst up to 2100 bar) and heavy mechanical loads, it features an integrated valve that permits safe coupling/uncoupling under residual pressure. Constructed from galvanized carbon steel with durable NBR sealing, it withstands wear, corrosion and harsh conditions, and operates from −25°C to +100°C. Flow capacities (16.4 l/min for 1/4", 21.3 l/min for 3/8" at Δp = 4 bar) and optional steel protective caps further support reliable, long-lasting performance in demanding applications.

Can the CEJN 232 Quick Connect Screw Plug with NPT Valve, Carbon Steel be used safely in mobile rescue tools exposed to extreme mechanical shock and vibration?

Yes. The CEJN 232 Quick Connect Screw Plug with NPT Valve, Carbon Steel is specifically engineered for demanding, high-pressure hydraulic applications—including rescue tools—making it suitable for use in mobile rescue tools exposed to extreme mechanical shock and vibration. Key reasons: - Designed for heavy mechanical loads: intended use includes rescue tools, cutting equipment and lifting devices. - High working and burst pressures: 700 bar working pressure with burst ratings up to 2100 bar provides a large safety margin under dynamic loads. - Robust materials and sealing: galvanized carbon steel construction and durable NBR seals resist wear, corrosion and harsh conditions. - Safe operation under residual pressure: integrated valve allows safe connection/disconnection even with residual system pressure. - Wide temperature range: -25°C to +100°C supports diverse operational environments. - Additional protection: steel protective caps (available separately) can further protect the coupling in severe service. For maximum safety in mobile rescue units, ensure correct size/flow selection, proper installation, routine inspection, and use protective caps and compatible hydraulic components.
