Constructed from 304 stainless steel, this plug offers solid corrosion resistance in both wet and dry service environments. It uses a male NPT threaded connection and carries a 150 psi pressure rating, making it suitable for standard-pressure fluid and gas lines. Installation requires only a wrench on the square head drive, which provides positive grip without the risk of rounding. Plumbers, pipefitters, and HVAC technicians typically use this type of plug during pressure testing, system commissioning, or to cap unused branch outlets.\u003c\/p\u003e\u003cp\u003eThis plug fits 3\/8 inch threaded pipe connections and is appropriate for residential and light commercial piping systems where a stainless steel fitting is specified for corrosion resistance or material compatibility. Common applications include capping test ports, branch tees, and unused lateral connections in water, air, and compatible gas piping assemblies. The MNPT thread pattern is the industry-standard for domestic pipe systems.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e304 stainless steel construction for corrosion resistance in wet and dry service\u003c\/li\u003e\n\u003cli\u003eSquare head drive accepts standard wrench for secure installation and removal\u003c\/li\u003e\n\u003cli\u003eMNPT threaded connection matches standard domestic pipe thread profiles\u003c\/li\u003e\n\u003cli\u003e150 psi pressure rating suitable for standard-pressure piping applications\u003c\/li\u003e\n\u003cli\u003e3\/8 inch fitting size covers a common branch and test-port pipe size\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and general-use fitting for 3\/8 inch MNPT threaded pipe connections in standard-pressure plumbing, HVAC, and industrial piping systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by licensed plumbers or pipefitters in accordance with applicable IPC and IFGC codes. Shut off system pressure and depressurize the line completely before removing or installing any threaded pipe plug.
