Rated at 150 lb, this galvanized cap is used to close the end of a threaded pipe run in a piping system. The galvanized finish provides corrosion resistance for both indoor and outdoor installations. Licensed plumbers and pipefitters install this type of fitting during new construction, system modifications, or when capping off unused branch lines. Its malleable iron construction offers impact resistance and the ability to withstand system pressure without cracking under normal service conditions.\u003c\/p\u003e\u003cp\u003eThis pipe cap suits residential and commercial piping applications where a threaded, pressure-rated end closure is required. It is commonly used in water supply, gas distribution, and general-purpose piping systems that call for 150 lb malleable iron fittings. The FNPT thread pattern accepts a standard male NPT threaded pipe end, making it compatible with standard iron pipe installations across a wide range of trade applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1-1\/4 inch nominal size for standard iron pipe compatibility\u003c\/li\u003e\n\u003cli\u003eFNPT thread pattern for direct connection to male NPT pipe ends\u003c\/li\u003e\n\u003cli\u003e150 lb pressure class malleable iron construction\u003c\/li\u003e\n\u003cli\u003eGalvanized finish for corrosion resistance in wet or outdoor environments\u003c\/li\u003e\n\u003cli\u003eFIG 3124 designation for straightforward replacement sourcing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement fitting for 150 lb malleable iron threaded piping systems using 1-1\/4 inch nominal pipe with male NPT threads.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis fitting is installed by licensed plumbers or pipefitters in accordance with applicable local plumbing and mechanical codes.
