Value Collection 13384 Countersunk Hex Plug 1 in Malleable Iron

Product Description

The VALUE COLLECTION 13384 is a countersunk hex plug designed to seal threaded pipe openings in piping systems handling liquid or gas service. Constructed from malleable iron with a black finish, this plug is rated Class 150 and carries a 300 psi pressure rating, making it suitable for moderate-pressure applications in both gas and liquid lines. The countersunk hex drive allows the plug to sit flush or below the fitting face, useful in installations where a low-profile closure is required. This fitting is installed by plumbers, pipefitters, and HVAC technicians working on threaded malleable iron piping systems.

This plug is used in residential and light commercial piping installations where a threaded end cap or line closure is needed. Its 1-inch threaded connection fits standard NPT female threaded ports on pipe fittings, valves, and manifolds. Common applications include capping unused branch outlets, sealing test points, and closing off service ports during system commissioning or repair. The black finish is standard for gas-service malleable iron fittings and is consistent with typical Class 150 black iron pipe system components.

Installation Notes

Installation is performed by licensed plumbers or pipefitters working on threaded iron piping systems. Shut off and depressurize the line before removing or installing any threaded plug. Apply an appropriate thread sealant or PTFE tape to male threads before installation, following applicable code requirements such as the International Fuel Gas Code (IFGC) or International Plumbing Code (IPC). Do not overtighten, as malleable iron threads can be damaged by excessive torque.
