Mueller Industries H-15428 1 in Mip X Compression Coupling

Product Description

The MUELLER INDUSTRIES H-15428 is a 1-inch MIP x compression coupling designed for making secure, leak-resistant transitions between male iron pipe (MIP) threaded connections and compression-style tubing in plumbing systems. This fitting uses a threaded male end on one side and a compression nut and ferrule arrangement on the other, allowing technicians to join dissimilar connection types without soldering or specialized tooling. It is a standard plumbing fitting typically installed by licensed plumbers in residential and light commercial water supply applications.

This coupling is suited for water supply piping where a threaded pipe needs to transition to a compression-connected tube run. The 1-inch size makes it appropriate for main branch or larger sub-branch supply lines. Installers working on fixture connections, shutoff valve installations, or pipe repairs where a compression-to-MIP transition is required will find this fitting applicable to those scenarios.

Key Features

• 1-inch MIP threaded end for connection to standard male iron pipe threads
• Compression-style opposite end eliminates the need for soldering or crimping
• Coupling configuration allows straight-line connection between two pipe or tube runs
• Compatible with typical compression ferrule and nut assemblies used in plumbing trade work

Compatibility

Designed as an OEM-style replacement or standard service fitting for 1-inch MIP x compression plumbing connections in residential and light commercial water supply systems.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and IPC standards. Shut off and depressurize the water supply line completely before beginning work. Hand-tighten the compression nut before applying a wrench, and avoid overtightening, which can damage the ferrule or distort the tubing. Inspect the compression seat and ferrule for debris or deformation before assembly.
