B K Mueller 511-228HC 2 Inch Galvanized Merchant Coupling

Product Description

The B K Mueller Industries 511-228HC is a 2-inch galvanized merchant coupling designed for joining threaded pipe sections in plumbing and piping systems. Constructed from steel with a hot-dip galvanized finish, this coupling provides corrosion resistance in water distribution, gas, and general-purpose piping applications. The full-thread-to-thread internal design ensures a secure mechanical connection without a center stop, allowing the coupling to be threaded onto pipe from either end. Plumbers and pipefitters rely on this style of fitting when a standard stop coupling cannot be inserted into an existing run without disassembling the line.

Merchant couplings are commonly used in repair situations where pipe must be coupled in place without removing adjacent fittings. This 2-inch fitting is suited for residential and light commercial plumbing, gas distribution piping, and industrial maintenance applications. The galvanized steel construction makes it appropriate for above-ground water supply, fire protection branch lines, and other systems where a durable threaded steel fitting is required by code or specification. Package quantity is 9 pieces per unit.

Key Features

• Full-thread-to-thread bore with no center stop, allowing installation on in-place pipe runs
• Galvanized steel construction for corrosion resistance in water and general-purpose piping
• 2-inch nominal pipe size for high-flow residential and light commercial applications
• Steel body rated for threaded pipe assembly per standard pipe fitting practices
• Sold in a package quantity of 9 pieces

Compatibility

Designed as an OEM-style replacement or maintenance fitting compatible with standard 2-inch NPT threaded steel pipe systems in plumbing, gas distribution, and general industrial piping.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with local plumbing codes and applicable sections of the IPC or IFGC. Shut off and depressurize the line before beginning any threaded pipe work. Apply appropriate thread sealant or PTFE tape to male threads before assembly, and hand-tighten before using a pipe wrench to achieve a proper seal. Do not over-torque, as this can crack fittings or damage pipe threads.
