Mueller Streamline ADP00924 Copper Adapter 1/4 in 50/box

Product Description

The MUELLER STREAMLINE ADP00924 is a wrot copper adapter fitting designed to transition between a female solder (sweat) connection and a male national pipe thread (MNPT) connection. At 1/4 inch on both ends, this adapter is built for tight-access refrigeration, HVAC, and plumbing lines where a reliable copper-to-threaded transition is required. The fitting measures 1.07 inches in actual length. Wrot copper construction ensures pressure integrity and compatibility with standard soldering practice. HVAC technicians and plumbers install this fitting when connecting copper tubing runs to threaded components such as valves, gauges, or service ports. Sold in a box of 50 units, it suits contractors stocking for multiple jobs.

This adapter is used in residential and light commercial HVAC, refrigeration, and plumbing applications wherever a 1/4 inch copper sweat connection must mate to a 1/4 inch male threaded fitting. Typical scenarios include connecting service valves, access fittings, or instrument tees into small-diameter copper line sets. The 50-per-box packaging makes it a practical stock item for service vans and shop inventory.
