This plug features a male x female NPT thread configuration in 3/8 inch size and a 7/8 inch body diameter. The body is constructed from steel with a zinc finish, providing corrosion resistance in typical shop and industrial environments. It is installed by HVAC technicians, plumbers, pipefitters, and general maintenance trades wherever quick-disconnect pneumatic fittings are required.

This quick connect plug is suited for residential and commercial applications where standard NPT pneumatic connections are used. Typical install scenarios include compressed air distribution lines, pneumatic tool hookups, and air-powered equipment service drops. The male x female NPT thread design allows in-line installation without disrupting the flow path. It is compatible with standard quick connect coupler bodies that accept 3/8 inch NPT plug profiles.
Designed as a standard-profile quick connect plug for pneumatic systems using 3/8 inch NPT fittings and couplers that accept a 7/8 inch body diameter plug.
Installation is typically performed by maintenance technicians or pipefitters working on compressed air systems. Depressurize and bleed down the air line completely before removing or installing any pneumatic fitting. Apply thread sealant appropriate for air service to the NPT threads per manufacturer practice. Refer to applicable facility or OSHA compressed air safety guidelines during service.
