Value Collection 13130 Countersunk Hex Plug 3/8 in Malleable Iron

Product Description

The VALUE COLLECTION 13130 is a black countersunk hex plug designed to seal threaded pipe openings in piping assemblies. Manufactured from malleable iron with a galvanized finish, this plug meets Class 150 standards and carries a liquid and gas pressure rating of 300 psi. The countersunk hex drive allows installation using a standard hex key or Allen wrench, making it well suited for tight spaces where a conventional square-head plug cannot be turned. Plumbers, pipefitters, and mechanical contractors install this fitting during system assembly or when capping unused branch outlets.

This plug is appropriate for use in residential and light commercial piping systems handling water, gas, air, and other compatible media within its rated pressure limits. The threaded end connection follows standard NPT pipe thread sizing at 3/8 inch, fitting directly into matching female-threaded fittings, valves, or manifolds. The galvanized finish provides a baseline level of corrosion resistance suited to typical indoor mechanical room and utility environments.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable IPC or IFGC requirements for the fluid or gas being handled. Shut off and depressurize the system completely before removing or installing any threaded plug. Apply an appropriate thread sealant or PTFE tape to the male threads before installation. Do not overtighten, as malleable iron fittings can crack under excessive torque.
