Elkhart Products 10031678 Copper 90 Reducing Elbow 1/2x3/8

Product Description

The ELKHART PRODUCTS 10031678 is a long-turn 90-degree reducing elbow designed for copper tube systems in residential and light commercial plumbing and HVAC applications. Manufactured from wrot copper with a solder-joint (sweat) connection, this fitting transitions from a 1/2-inch line to a 3/8-inch line while maintaining smooth directional flow through the long-turn geometry. At 0.065 pounds, it is a compact, lightweight fitting well suited for close-quarters rough-in work. Plumbers and HVAC technicians install this fitting wherever a directional change and a simultaneous size reduction are needed in a copper tube run.

This reducing elbow is used in potable water supply lines, refrigerant tubing systems, and hydronic distribution lines where a 90-degree turn and a step-down from 1/2 inch to 3/8 inch are required in a single fitting. The long-turn radius reduces turbulence and pressure drop compared to a standard short-turn elbow, making it a preferred choice in higher-flow or noise-sensitive installations. The sweat connection is compatible with standard 95-5 or lead-free solder per applicable plumbing codes.

Key Features

• Long-turn 90-degree geometry reduces flow turbulence and pressure drop
• Wrot copper construction for durability and compatibility with copper tube systems
• Sweat (solder) C x C connection for a reliable, leak-tight joint
• Reduces from 1/2 inch to 3/8 inch in a single fitting, eliminating an additional reducer
• Compact footprint at 1.46 x 1.37 x 0.70 inches for use in tight spaces

Compatibility

Designed as an OEM-style replacement or new-installation fitting for copper tube systems using standard C x C sweat connections in 1/2-inch and 3/8-inch line sizes.

Installation Notes

Installation is performed by licensed plumbers or HVAC technicians. Shut off and depressurize the water or refrigerant system before cutting into any existing line. Clean tube ends and fitting cups thoroughly with emery cloth and apply flux before soldering per ASTM and local plumbing code requirements. Follow applicable IPC or IFGC guidelines for solder type and joint inspection.
