B K Mueller Industries 511-200HC Galvanized Coupling 1/8 in

Product Description

The B K Mueller Industries 511-200HC is a galvanized coupling with an integrated stop, designed for use in threaded pipe assemblies. The stop shoulder prevents over-insertion, keeping pipe ends positioned correctly within the fitting and simplifying alignment during assembly. At 1/8 inches, this coupling is suited for small-diameter piping runs where consistent thread engagement and corrosion resistance are required. The galvanized finish provides a protective zinc coating that extends service life in moderate-moisture environments. This type of fitting is handled by licensed plumbers and pipefitters during new construction, maintenance, and repair work on low-pressure pipe systems.

This coupling is appropriate for residential and light commercial plumbing and gas piping applications involving 1/8-inch threaded pipe. It is typically used in branch lines, instrument connections, and other small-diameter runs where a secure, repeatable joint is needed. The with-stop design is especially useful in tight spaces where visual confirmation of pipe seating is difficult. Each package contains 25 units, making it practical for contractors stocking jobsite supplies or service vans.

Installation Notes

Installation is performed by a licensed plumber or pipefitter. Shut off and depressurize the pipe system before removing or installing any threaded fitting. Apply appropriate thread sealant or PTFE tape to male threads before assembly. Follow applicable IPC or IFGC requirements for the specific piping system type and service pressure.
