B K/mueller Inds(import) 511-700HC Galvanized Union

Product Description

The B K/MUELLER INDS(IMPORT) 511-700HC is a 1/8 inch galvanized steel union fitting used to join and disconnect threaded pipe sections in low-pressure piping systems. Galvanized construction provides corrosion resistance suitable for gas, water, and general plumbing distribution lines. This union allows pipe runs to be separated without disturbing adjacent fittings, making it a standard component for service and repair work. Plumbers and pipefitters install this fitting in both new construction and retrofit applications where a threaded, demountable connection is required.

This 1/8 inch union is sized for small-diameter threaded pipe runs commonly found in residential and light commercial gas distribution, water supply, and compressed air systems. It is sold in package quantities of 35 units, making it practical for contractors stocking fittings for multiple jobs or for supply house distribution. Installation follows standard NPT threading practices.

Key Features

• Galvanized steel construction for corrosion resistance in moisture-prone and outdoor environments
• 1/8 inch nominal pipe size for small-diameter threaded connections
• Union design allows pipe sections to be disconnected without unthreading entire runs
• Packaged in quantities of 35 units per package for contractor and distributor stocking
• Standard NPT thread form for compatibility with common threaded pipe and fittings

Compatibility

Designed as an OEM-style replacement and standard-stock union fitting for 1/8 inch NPT threaded pipe systems in plumbing, gas, and general piping applications.

Installation Notes

Installation is performed by licensed plumbers or pipefitters following applicable IPC or IFGC code requirements for the system type. Shut off and depressurize the line before disassembly or installation. Apply an appropriate pipe thread sealant or PTFE tape to all male threads before assembly. Do not over-tighten galvanized fittings, as this can crack the zinc coating and damage threads.
