Mueller Streamline bk-105-784nl Meter Coupling 3/4 in

Product Description

The MUELLER STREAMLINE bk-105-784nl is a lead-free water meter coupling designed for use in potable water plumbing systems. Built from heavy brass construction, this 3/4-inch coupling connects water meters to supply lines using threaded ends that comply with ANSI B2.1 standards. The wetted surfaces contain no more than 0.25 percent weighted average lead content, meeting low-lead requirements for drinking water applications. It is rated to 125 psi and is a standard service component installed by licensed plumbers in residential and light commercial meter settings.

This meter coupling is intended for use with plumbing valves and water meter installations at the service entry point. The 3/4-inch nominal size fits the most common residential water meter configurations. It is appropriate for potable water service lines where lead-free materials are required by code, including installations subject to state and local low-lead plumbing mandates.

Installation Notes

Installation should be performed by a licensed plumber in accordance with local plumbing codes and the International Plumbing Code (IPC).

Apply appropriate thread sealant or PTFE tape to threaded connections as required by the fitting manufacturer and local code.
