Value Collection 13128 Countersunk Hex Plug 1/8 in Malleable Iron

Product Description

The VALUE COLLECTION 13128 is a countersunk hex plug designed to close off threaded pipe openings in low- and medium-pressure piping systems. Constructed from malleable iron with a galvanized finish, this plug provides corrosion resistance suitable for both liquid and gas service. It carries a Class 150 pressure classification with a rated working pressure of 300 psi. The 1/8 inch threaded end connection allows direct installation into standard NPT female fittings. Plumbers, pipefitters, and mechanical contractors use this type of plug to cap unused ports on valves, manifolds, tees, and other threaded fittings during system assembly or maintenance.

This countersunk hex plug is suited for residential and light commercial plumbing, HVAC hydronic systems, compressed air lines, and general gas piping applications where a low-profile, flush-seated plug is required. The countersunk hex drive allows installation and removal with a hex key in tight spaces where a standard hex head plug would not clear surrounding components. It is sold in packages of 10 units, making it a practical choice for contractors stocking commonly used fittings.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local plumbing and mechanical codes. Shut off and depressurize the system completely before installing or removing any threaded plug. Apply an appropriate thread sealant or PTFE tape to the male threads before installation. Use the correct hex key size to avoid stripping the countersunk drive socket.
