B K/mueller Inds(import) 511-702HN 3/8 in Galvanized Union

Product Description

The B K/MUELLER INDS(IMPORT) 511-702HN is a 3/8 inch galvanized union constructed with brass and iron materials. A union fitting allows a pipe run to be disconnected and reconnected without cutting or threading additional pipe, making it a standard component in gas, water, and general plumbing distribution systems. The galvanized finish provides corrosion resistance suited to exposed or mildly corrosive service environments. This fitting is sold in a package of 10 units, making it practical for contractors stocking job-site inventory or completing multi-connection installations in a single trip.

This galvanized union is used in residential and light commercial plumbing and mechanical piping systems where 3/8 inch pipe connections require a serviceable, disconnect-capable joint. Typical applications include supply branch lines, appliance connections, and general pipe repairs where threaded galvanized pipe is the specified material. Licensed plumbers and pipefitters are the primary installers for this type of fitting in code-regulated work.

Key Features

• 3/8 inch pipe size for standard threaded galvanized pipe systems
• Galvanized finish for corrosion resistance in exposed or damp environments
• Brass and iron construction for durability at threaded joints
• Union design allows disconnection without disturbing the surrounding pipe run
• Packaged in quantities of 10 for contractor and wholesale use

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 3/8 inch threaded galvanized pipe systems in residential and commercial plumbing applications.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and IPC requirements. Shut off and depressurize the affected pipe system before disassembling or installing union fittings. Apply appropriate thread sealant or PTFE tape to all male threads before assembly. Do not over-tighten the union nut, as this can distort seating surfaces and cause leaks.
