Mueller Streamline CPL00962 Reducing Coupling 3/4x1/4 Copper

Product Description

The MUELLER STREAMLINE CPL00962 is a wrot copper reducing coupling designed to connect two copper tubing lines of different diameters in a single sweat-solder joint. It transitions from a 3/4-inch to a 1/4-inch connection using a C x C (copper by copper) configuration, making it a standard fitting for refrigeration, HVAC, and plumbing applications. The fitting measures 1.44 inches in length and 0.97 inches in both height and width, with a lightweight construction at 0.06 pounds. Licensed plumbers and HVAC technicians are the primary installers of this fitting in new construction and service work.

This reducing coupling is suited for residential and light commercial installations where a sweat-soldered copper transition is required between 3/4-inch OD and 1/4-inch OD tubing. Common applications include refrigerant line modifications, potable water distribution, and hydronic piping systems. It meets ASME and NSF standards, making it appropriate for both pressure-rated and potable water service where copper fittings are specified.

Key Features

• Wrot copper construction for reliable sweat-solder joints and corrosion resistance
• C x C connection type compatible with standard copper tubing and sweat fittings
• Transitions 3/4-inch to 1/4-inch OD tubing in a compact 1.44-inch length
• Meets ASME and NSF compliance standards for pressure and potable water applications
• Lightweight at 0.06 pounds for easy handling in tight spaces

Compatibility

Designed as an OEM-style sweat fitting for use with standard copper tubing in residential and light commercial plumbing and HVAC piping systems requiring a 3/4-inch to 1/4-inch reduction.

Installation Notes

Installation requires shutting off the water supply or recovering refrigerant before cutting into any existing line. A licensed plumber or HVAC technician should perform the sweat-solder connection using proper flux, solder, and a torch rated for copper fittings. Tubing ends must be cut cleanly, deburred, and cleaned before soldering to ensure a leak-free joint. Work should comply with applicable local plumbing codes and ASME guidelines.
