B K/mueller Inds(import) 511-405HN 1 Inch Galvanized Cap

Product Description

The B K/MUELLER INDS(IMPORT) 511-405HN is a 1-inch galvanized pipe cap designed to terminate or seal the end of a threaded pipe. Galvanized construction provides corrosion resistance suited for water supply, gas distribution, and general plumbing applications. The cap threads onto the outside of a male-threaded pipe end, creating a secure, pressure-rated closure. Licensed plumbers and pipefitters install these caps during system construction, pressure testing, and pipe-end capping on live or inactive lines. Sold in a package of 10 units, making it practical for contractors who need to cap multiple lines on a single job.

This galvanized cap is suited for residential and light commercial plumbing and piping systems where threaded galvanized steel pipe is present. Common applications include capping branch tees during phased construction, isolating unused outlets on gas manifolds, and sealing pipe ends on water distribution lines. The 1-inch size fits standard Schedule 40 NPT-threaded galvanized pipe.

Installation Notes

Installation is performed by licensed plumbers or pipefitters in accordance with applicable IPC or IFGC requirements. Shut off water or gas supply and depressurize the line before threading the cap onto the pipe end. Apply pipe thread sealant or PTFE tape to the male threads before installation. Do not overtighten by pipe wrench to the point of cracking the fitting; hand-tighten and finish with a wrench for a snug, leak-free seal.
