Elkhart Products 10030680 Reducer Coupling with Stop

Product Description

The ELKHART PRODUCTS 10030680 is a wrot copper reducer coupling with stop, designed to transition between 3/8 inch OD and 5/16 inch OD copper tubing using a sweat solder (C x C) connection. The integral stop positions the tubing at the correct depth for a consistent, leak-free joint. This fitting is manufactured from wrot copper, which offers superior pressure ratings and long-term corrosion resistance compared to cast alternatives. Weighing just 0.008 pounds, it is a compact fitting suited for tight spaces in residential and light commercial plumbing and HVAC refrigerant line applications.

This reducer coupling is used wherever a size transition is required between 3/8 inch OD and 5/16 inch OD copper tubing runs. Typical applications include residential plumbing supply lines, hydronic heating distribution piping, and HVAC refrigerant or condensate line assemblies. The C x C sweat connection makes it compatible with standard torch-and-solder installation workflows used by licensed plumbers and HVAC technicians.

Key Features

• Wrot copper construction for high-pressure integrity and corrosion resistance
• Integral stop ensures correct tubing insertion depth for a consistent solder joint
• 3/8 inch OD to 5/16 inch OD reduction in a single compact fitting
• C x C sweat solder connection compatible with standard torch-and-solder technique
• Lightweight at 0.008 pounds, suitable for confined installation spaces

Compatibility

Designed as an OEM-style replacement or new-installation fitting for copper tubing systems using 3/8 inch OD and 5/16 inch OD sweat connections in plumbing and HVAC applications.

Installation Notes

Installation should be performed by a licensed plumber or HVAC technician following applicable local plumbing codes and IFGC or IPC guidelines where referenced. Shut off and depressurize the supply line and allow existing piping to cool completely before cutting or fitting. Clean and flux all mating surfaces before applying heat, and use lead-free solder where potable water systems are involved. Allow the joint to cool fully before restoring pressure to the system.
