Constructed from malleable iron with a black finish, this plug meets Class 150 standards and carries a liquid and gas pressure rating of 300 psi. The 1-1\/4 inch threaded connection allows direct installation into standard female-threaded fittings without additional adapters. Licensed plumbers and pipefitters install this type of plug to cap unused branch outlets, close test ports, or terminate dead-end runs during system commissioning or modification.\u003c\/p\u003e\n\u003cp\u003eThis countersunk square plug is suited for residential and light commercial piping applications where a low-profile, flush-seating closure is required. The countersunk head design sits recessed or flush against the fitting face, reducing protrusion in tight spaces. It is commonly used in gas distribution, steam, water, and compressed air piping systems that operate within Class 150 pressure limits. The threaded end connection is compatible with standard NPT female threads at 1-1\/4 inch nominal pipe size.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMalleable iron construction provides durability in moderate-pressure piping systems\u003c\/li\u003e\n  \u003cli\u003eBlack finish suitable for gas and steam service applications\u003c\/li\u003e\n  \u003cli\u003eRated to 300 psi for liquid and gas service\u003c\/li\u003e\n  \u003cli\u003eClass 150 classification for use in standard low-to-medium pressure systems\u003c\/li\u003e\n  \u003cli\u003eCountersunk square head profile for reduced protrusion in confined spaces\u003c\/li\u003e\n  \u003cli\u003eThreaded end connection for direct installation into NPT female fittings\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard-stock threaded plug for 1-1\/4 inch NPT female-threaded pipe fittings in Class 150 malleable iron piping systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a licensed plumber or pipefitter using a square-drive or appropriate wrench sized for the countersunk head.
