B K/mueller Inds(import) 511-402HN Galvanized Pipe Cap

Product Description

The B K/MUELLER INDS(IMPORT) 511-402HN is a 3/8-inch galvanized pipe cap used to terminate open pipe ends in water, gas, and general plumbing systems. The cap threads onto the end of a male-threaded pipe, creating a secure, sealed closure that prevents flow, contamination, or pressure loss at unused outlets. The hot-dip galvanized coating provides corrosion resistance in moist or exposed environments. Plumbers and pipefitters install this fitting during new construction, system modifications, or when capping off branch lines that are no longer in service.

This 3/8-inch cap is suited for residential and light commercial plumbing and gas distribution systems where threaded galvanized fittings are specified. It is a standard end cap used on Schedule 40 galvanized pipe runs to close off tees, laterals, or stub-outs. The fitting is sold in packages of 10 units, making it a practical stocking item for service trucks and supply rooms handling routine pipe work.

Installation Notes

Installation is performed by licensed plumbers or pipefitters in accordance with applicable plumbing and mechanical codes such as the IPC or IFGC. Always shut off the water or gas supply and depressurize the line before installing or removing any threaded pipe fitting. Apply appropriate thread sealant or PTFE tape to the male threads before threading on the cap. Do not overtighten, as this can crack the fitting or damage threads.
