Asc Engineered Solutions 8700159851 Galvanized Plug 1/2 in

Product Description

The ASC Engineered Solutions 8700159851 is a 1/2-inch malleable iron galvanized plug designed to close off the end of a threaded pipe fitting or fitting port. The hollow-core design keeps weight low while maintaining the structural integrity expected from malleable iron construction. The exterior galvanized coating provides corrosion resistance for use in both dry and wet piping environments. This plug is a standard trade item installed by licensed plumbers and pipefitters on water, gas, and general mechanical piping systems where an open threaded port needs to be sealed.

This plug is suited for residential and light commercial plumbing and mechanical piping applications. It is commonly used during pressure testing to temporarily cap off lines, or as a permanent closure on unused outlet ports. The 1/2-inch NPT thread size fits the most common small-diameter pipe branches found in water supply, gas distribution, and hydronic heating systems. Installation requires only a pipe wrench and compatible thread sealant or thread tape.

Installation Notes

Installation is performed by a licensed plumber or pipefitter. Before installing, depressurize and isolate the line being serviced per local code requirements. Apply an appropriate thread sealant compound or PTFE tape to the male threads before tightening. Do not overtighten malleable iron fittings, as excessive force can crack the casting.
