Elkhart Products MA-1 Copper Male Adapter 1 Inch Cxm

Product Description

The ELKHART PRODUCTS MA-1 is a 1-inch copper male adapter designed for sweat-solder connections in residential and commercial plumbing systems. Part of the KLEENFIT product line, this fitting ships cleaned and bagged to meet flux-ready installation standards, reducing prep time on the job. It uses a copper-to-male-thread (CxM) connection type, allowing a soldered copper tube end to transition to a male-threaded fitting. Licensed plumbers and pipefitters install this adapter where copper supply lines need to connect to threaded valves, fixtures, or equipment. At 0.170 pounds, it is a lightweight, single-use transition fitting suited for potable water, hydronic, and general plumbing applications.

This adapter is used in residential and light commercial plumbing installations where a 1-inch copper tubing run must terminate at a male-threaded connection point. Common applications include water supply rough-in, boiler piping, and fixture connections. The KLEENFIT designation means the fitting is factory-cleaned and bagged, making it ready for immediate soldering without additional degreasing or cleaning steps in the field.

Key Features

• Copper construction for corrosion resistance in potable water and hydronic systems
• CxM (copper sweat to male thread) connection for transitioning from soldered copper to threaded fittings
• KLEENFIT factory-cleaned and bagged for flux-ready, immediate installation
• Solder-type joint for a reliable, leak-resistant connection
• Lightweight at 0.170 pounds for easy handling in tight spaces

Compatibility

Designed as an OEM-style replacement and standard-use fitting for 1-inch copper tubing systems using sweat-solder CxM connections in residential and commercial plumbing applications.

Installation Notes

Installation should be performed by a licensed plumber in accordance with IPC and applicable local plumbing codes. Shut off and depressurize the water supply line before cutting or fitting copper tubing. Clean the tube end and apply appropriate flux before soldering; the KLEENFIT cleaning removes manufacturing residue but field flux is still required. Allow the joint to fully cool before restoring pressure and inspecting for leaks.
