The male thread is sized 1\/4-18 MNPT, allowing it to seat into a standard female NPT port and seal under pressures up to 1,000 psi. The hollow hex drive profile accepts a hex key for installation and removal without requiring external wrench flats, making it suitable for tight-clearance locations. Licensed plumbers, pipefitters, and HVAC-R technicians install this type of plug during system assembly, maintenance, and pressure testing procedures.\u003c\/p\u003e\n\u003cp\u003eThis plug is suited for residential and light commercial piping applications where a low-profile port closure is needed. Typical uses include capping unused branch ports on manifolds, gas valves, and distribution assemblies. Its lead free brass construction meets potable water requirements, making it appropriate for domestic plumbing systems in addition to fuel gas and lubrication service lines. The 1\/4-18 MNPT thread is one of the most common pipe thread sizes found in trade plumbing and HVAC piping assemblies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLead free brass construction meets potable water compliance requirements\u003c\/li\u003e\n  \u003cli\u003e1\/4-18 MNPT male thread seats into standard female NPT ports\u003c\/li\u003e\n  \u003cli\u003eRated to 1,000 psi maximum working pressure\u003c\/li\u003e\n  \u003cli\u003eHollow hex drive allows installation with a hex key in confined spaces\u003c\/li\u003e\n  \u003cli\u003eCompatible with potable water, grease, fuels, LP gas, and natural gas service\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eRated for use with potable water, grease, fuels, LP gas, and natural gas systems.
