Can the NPT GW quick-connect screw plug with valve, carbon steel, PVS type be connected or disconnected under residual pressure up to 700 bar without leakage or damage?

Yes. The NPT GW quick-connect screw plug with valve, carbon steel, PVS type is designed to be connected and disconnected under residual pressure. The product description explicitly states it "can be connected/disconnected when there is residual pressure in the system." Its rated working pressure is 700 bar and burst pressures for connected and disconnected conditions are provided (e.g., 1/4" disconnected coupling burst 1490 bar, connected 2100 bar), indicating it is engineered for very highâpressure applications. Seals are NBR and materials are carbon steel; maximum operating temperature range is -25Â°C to +100Â°C. Caveats: follow manufacturer instructions, use correct end caps, ensure the residual pressure does not exceed the specified working/burst limits, verify compatibility with fluids and temperature, and perform connections with proper protective procedures to avoid risk.

Is the NPT GW quick-connect screw plug with valve, carbon steel, PVS type suitable for use in hydraulic presses at 700 bar?

Yes. The NPT GW quick-connect screw plug with valve, carbon steel, PVS type is suitable for use in hydraulic presses at 700 bar: its working pressure is rated 700 bar, materials (carbon steel, NBR seals) and wide operating temperature (-25Â°C to +100Â°C) match typical press service, and burst pressures far exceed 700 bar when connected. Note: ensure correct size (1/4" or 3/8") for required flow, fit end caps (ordered separately), and verify compatibility with your fluid and any specific system safety factors.

Does the NPT GW quick-connect screw plug with valve, carbon steel, PVS type require end caps for storage and transport?

Yes. The NPT GW quick-connect screw plug with valve, carbon steel, PVS type requires end caps for storage and transport. End caps must be ordered separately.
