Threaded with a male NPT (MNPT) end, this plug is rated at 125 lb pressure class and manufactured from rough brass for reliable sealing in plumbing, HVAC hydronic, and general piping applications. The nominal size is 1-1\/2 inches. Licensed plumbers and pipefitters install this type of plug during system assembly, testing, and service work where a pressure-rated pipe closure is required.\u003c\/p\u003e\n\u003cp\u003eThis plug is suited for residential and light commercial piping installations where brass fittings are specified. Common applications include closing unused branch outlets, capping test ports, and plugging open ends during pressure testing on water, steam, and air distribution systems.
