Elkhart Products MA-34X1 Male Reducing Adapter 3/4x1 Copper

Product Description

The ELKHART PRODUCTS MA-34X1 is a wrot copper male reducing adapter designed for sweat-solder copper tubing systems. This fitting transitions from a 3/4-inch copper tube (C) end to a 1-inch male threaded (M) end, allowing a copper run to connect to a larger threaded fitting or valve body. At 0.234 pounds, it is a compact, lightweight fitting machined from wrot copper for consistent wall thickness and reliable soldered joints. Plumbers and pipefitters install this adapter in potable water, hydronic heating, and general plumbing distribution systems where a pipe-size step-up and a transition from solder to threaded connection is required.

This adapter is suited for residential and light commercial plumbing applications where copper tubing transitions to a larger threaded male connection. Typical installations include tie-ins at water heater inlets and outlets, manifold connections, and shut-off valve assemblies where a 3/4-inch copper line feeds a 1-inch threaded port. The C x M configuration means the 3/4-inch end accepts a standard copper tube for soldering, while the 1-inch end is an externally threaded male fitting that threads into a female-threaded port.

Key Features

• Wrot copper construction provides consistent grain structure and reliable solder joints
• C x M configuration transitions 3/4-inch sweat copper to 1-inch male threads
• Solder-type cup end conforms to standard copper tube OD for clean, leak-free joints
• Compact dimensions: 1.43 x 1.62 x 1.27 inches for installation in tight spaces
• Lightweight at 0.234 pounds, minimizing added load on pipe runs

Compatibility

Designed as an OEM-style wrot copper solder fitting compatible with standard 3/4-inch copper tube on the sweat end and standard 1-inch male NPT threaded connections on the male end, suitable for potable water and hydronic plumbing systems.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable IPC or local plumbing codes. Shut off and drain the water supply before cutting into any existing pipe. Clean and flux both the copper tube and the fitting cup thoroughly before applying heat to ensure a full, void-free solder joint. Do not apply thread sealant or tape to the male threaded end until the soldered joint has fully cooled.
