Is the Pneumatic quick-connect socket with GZ, carbon steel, CEJN 320 VS safe to disconnect under pressure?

Pneumatic quick-connect socket with GZ, carbon steel, CEJN 320 VS is not safe to disconnect under pressure. The CEJN series 320 in VS version is explicitly designed for disconnection without pressure to avoid the risk of recoil and is compliant with ISO 4414 and EN 983 standards. Its VS (safety) design requires the circuit to be depressurised before separation. Working pressure is rated to 12 bar with a safety factor 4:1, but disconnection under live pressure would create a hazardous recoil risk. Always relieve system pressure before disconnecting.

Can the Pneumatic quick-connect socket with GZ, carbon steel, CEJN 320 VS be used safely at 12 bar in industrial pneumatic systems?

Yes. The Pneumatic quick-connect socket with GZ, carbon steel, CEJN 320 VS can be used safely at 12 bar in industrial pneumatic systems. It is rated for a working pressure of 12 bar with a 4:1 safety factor, complies with ISO 4414 and EN 983 (VS version ensures disconnection only without pressure to prevent recoil), and is designed for industrial pneumatic installations. Materials and seals (galvanized steel, NBR) and operating temperature range (-20Â°C to +100Â°C) are suitable for typical pneumatic use. Ensure correct BSPT thread installation, compatibility with mating couplers, and regular inspection and maintenance per manufacturer guidelines.

Can the Pneumatic quick-connect socket with GZ, carbon steel, CEJN 320 VS be used with NBR seals at -20Â°C?

Yes. Pneumatic quick-connect socket with GZ, carbon steel, CEJN 320 VS can be used with NBR seals at â20Â°C. The product specification states sealing: NBR and operating temperature range: from â20Â°C to +100Â°C, so â20Â°C is within the approved limits. Ensure application-specific checks (dynamic vs. static sealing, exposure to oils/chemicals, pressure cycling) but per manufacturer data the NBR seal is rated for that minimum temperature.
