Can the NPT GZ quick-connection screw socket with valve, carbon steel, PVS type be connected or disconnected under residual system pressure up to 700 bar?

Yes. The NPT GZ quick-connection screw socket with valve, carbon steel, PVS type can be connected and disconnected when there is residual system pressure present, up to its specified working pressure of 700 bar. The product description explicitly states it "can be connected/disconnected when there is residual pressure in the system." Ensure end caps are used (ordered separately) and observe all operating limits (sealing material NBR, temperature â25Â°C to +100Â°C) and safety margins relative to burst pressures.

Is the NPT GZ quick-connection screw socket with valve, carbon steel, PVS type suitable for rescue equipment at 700 bar?

Yes. The NPT GZ quick-connection screw socket with valve, carbon steel, PVS type is suitable for rescue equipment at 700 bar. It is designed for very high-pressure installations and mechanically demanding applications (including rescue equipment), allows connection/disconnection under residual pressure, has a working pressure of 700 bar, appropriate burst pressures when connected, and an operating temperature range of -25Â°C to +100Â°C. Ensure correct size (1/4" or 3/8"), use specified NBR sealing, and order end caps separately.

Does the NPT GZ quick-connection screw socket with valve, carbon steel, PVS type require end caps sold separately?

Yes. The NPT GZ quick-connection screw socket with valve, carbon steel, PVS type requires end caps to be ordered separately (end caps must be ordered separately).
