B K/mueller Inds(import) 511-806HN Galvanized Pipe Plug

Product Description

The B K/MUELLER INDS(IMPORT) 511-806HN is a 1-1/4 inch galvanized, plain forged pipe plug used to cap or seal threaded pipe openings in plumbing, gas distribution, and mechanical piping systems. Constructed through a forging process for added material integrity, this plug features a hot-dip or mill galvanized finish that provides corrosion resistance in wet and exposed environments. Plumbers and pipefitters install this type of plug to temporarily or permanently close male NPT-threaded fittings during pressure testing, system modification, or final commissioning. Each package contains 5 plugs, making it practical for service trucks and job-site inventory.

This 1-1/4 inch galvanized plug is suited for residential and commercial plumbing rough-in work, industrial pipe systems, and HVAC hydronic piping where iron or steel pipe is used. It is commonly installed in water supply, drain, waste and vent, gas piping, and compressed air lines that use standard NPT threaded connections. The forged construction makes it appropriate for applications that require a solid, dependable seal under normal working pressures. It is sold in a package of 5 units, which is well-suited for contractors stocking multiple sizes on the job.
