Mueller Industries W 01525 Copper Pipe Adapter 3/8 in

Product Description

The MUELLER INDUSTRIES W 01525 is a wrot copper pipe adapter designed for solder-joint connections in copper piping systems. It features a fitting-to-female (FTG x F) end connection, allowing a copper tube or fitting spigot end to join a female socket end in a single sweat connection. The fitting size is 3/8 inch with an outside diameter of 1/2 x 3/8 inches. Weighing 0.0487 pounds, this adapter is compact and suited for tight spaces. Licensed plumbers and HVAC technicians install this fitting in both residential and light commercial copper piping assemblies.

This adapter is commonly used in domestic water supply, hydronic heating, and HVAC refrigerant or condensate piping where a transition between a spigot end and a female socket is required. Its wrot copper construction makes it appropriate for use in pressure applications and systems requiring reliable, leak-free solder joints. It is sold individually and is suitable for new installation or repair work on 3/8-inch copper line sets and branch connections.

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 3/8-inch copper piping systems using standard solder-joint (sweat) connections per ASME B16.22.

Installation Notes

Installation should be performed by a licensed plumber or qualified HVAC technician in accordance with applicable local plumbing codes and ASME standards. Shut off and depressurize the water or fluid system completely before cutting or fitting any piping. Clean and flux all mating surfaces thoroughly before applying heat; overheating wrot copper fittings can damage the fitting and compromise joint integrity. Follow IPC or applicable local code requirements for solder type, particularly on potable water systems where lead-free solder is mandated.
