Mueller Industries W 01901 Copper Coupling 1/4 in C X C

Product Description

The MUELLER INDUSTRIES W 01901 is a wrot copper pipe coupling designed for 1/4 inch copper tubing connections using a C x C (copper-to-copper) solder joint configuration. This fitting provides a reliable, pressure-rated inline connection suitable for potable water, refrigeration, and general plumbing piping systems. Manufactured from wrot copper, it meets dimensional and performance requirements under multiple ASME standards. The outside diameter measures 3/8 inches. At 0.0064 pounds, it is a compact, lightweight fitting. Installation is performed by licensed plumbers and HVAC technicians using standard soldering equipment and flux.

This coupling is suited for residential and light commercial plumbing and refrigeration applications where a straight inline pipe extension or repair is needed. The C x C end connections accept copper tubing on both ends, making it a straightforward choice for connecting two lengths of 1/4 inch copper pipe or tubing. Typical applications include refrigerant line repairs, hydronic piping, and domestic water distribution systems.

Key Features

• Wrot copper construction for high-pressure and high-temperature durability
• C x C solder joint ends compatible with standard 1/4 inch copper tubing
• Outside diameter of 3/8 inches for dimensional consistency
• Compliant with ASME B16.22, ASME B16.18, and ASME B16.15 dimensional standards
• Lightweight at 0.0064 pounds for easy handling in tight spaces
• Meets ASME B1.20.1 thread and dimensional accuracy requirements

Compatibility

Designed as an OEM-style replacement and standard-service fitting for 1/4 inch copper tubing systems using sweat solder connections in plumbing and refrigeration piping applications.

Installation Notes

Installation of this fitting should be performed by a licensed plumber or HVAC technician in accordance with applicable local plumbing codes and ASME standards. Shut off and depressurize the supply line completely before cutting and preparing the pipe ends. Clean and flux all mating surfaces thoroughly before applying heat with a torch to ensure a full, void-free solder joint. Avoid overheating the fitting, as excessive heat can compromise the integrity of the solder connection.
