Mueller Industries BDNA-15649 Copper Pipe Adapter 1/2x3/8 Cxf

Product Description

The MUELLER INDUSTRIES BDNA-15649 is a wrot copper pipe adapter designed to transition between a 1/2-inch sweat (C) connection and a 3/8-inch female (F) threaded connection. Wrot copper construction provides superior pressure ratings and leak resistance compared to cast fittings, making it a standard choice in plumbing and HVAC refrigerant line applications. The outside diameter measures 5/8 inches on the sweat end and 3/8 inches on the female threaded end. Licensed plumbers and HVAC technicians install this fitting during new construction, remodel work, and system servicing where a copper-to-thread transition is required.

This adapter is used in residential and light commercial plumbing systems, hydronic heating lines, and HVAC refrigerant or condensate piping where a sweat-to-female-thread transition is needed. It is suited for tight spaces and standard rough-in configurations. The compact form factor allows installation in confined mechanical chases and equipment cabinets.

Installation Notes

Installation is performed by a licensed plumber or certified HVAC technician. Shut off the water supply or refrigerant circuit and depressurize the line before soldering. Clean and flux all sweat connections per standard practice before applying heat. Thread connections should be sealed with approved thread sealant or PTFE tape in accordance with applicable IPC or IFGC guidelines.
