Elkhart Products COU-114X34 Reducer Coupling 1-1/4x3/4 in

Product Description

The ELKHART PRODUCTS COU-114X34 is a wrought copper reducer coupling with stop, sized 1-1/4 inches by 3/4 inches, joining two sweat-end (C x C) copper tubing runs with a solder connection. The built-in stop positions the tubing accurately inside the fitting before soldering, ensuring consistent joint depth and reliable sealing. Wrought copper construction meets demanding pressure and temperature requirements common in residential and light commercial plumbing systems. This type of fitting is a staple for plumbers performing water distribution, hydronic, and HVAC refrigerant-line work where a step-down in pipe diameter is required.

This reducer coupling is suited for copper tubing installations in residential and commercial water supply, heating, and cooling piping systems. It transitions a 1-1/4-inch line down to a 3/4-inch line using standard soldering procedures. Licensed plumbers and HVAC technicians install this fitting wherever a diameter reduction is needed mid-run, such as branch takeoffs in domestic water systems or hydronic loops.

Key Features

• Wrought copper body for superior ductility and pressure integrity compared to cast fittings
• Built-in stop ensures correct tubing insertion depth for consistent solder joints
• C x C socket ends accept standard copper tubing for sweat soldering
• Reduces 1-1/4-inch tubing to 3/4-inch tubing in a single fitting
• Compact profile fits tight spaces within wall cavities and mechanical rooms

Compatibility

Designed as an OEM-style replacement and standard-service fitting for copper tubing plumbing systems requiring a 1-1/4-inch by 3/4-inch sweat-end reducer coupling.

Installation Notes

Installation is performed by a licensed plumber or qualified HVAC technician following applicable IPC and local plumbing codes. Shut off and drain the affected water or fluid line completely before cutting and fitting. Clean and flux all mating copper surfaces before applying heat; use lead-free solder where potable water applications are involved. Allow the joint to cool fully before restoring system pressure.
