The JMF COMPANY 2510108089800 is a wrot copper pipe adapter with a 1/2-inch female solder (slip) connection on one end and a 1/2-inch male NPT threaded connection on the other. Manufactured from C12200 copper per ASTM B75, this adapter transitions between a soldered copper line and a threaded fitting or valve body in a single compact fitting. It meets ASME/ANSI B16.22 and MSS SP-104 standards. Licensed plumbers and refrigeration technicians install this type of adapter in potable water, hydronic, and refrigeration piping systems where a copper run terminates at a threaded port.
This adapter is suited for residential, commercial, and industrial plumbing and refrigeration applications. It is commonly used where a copper supply line connects to a threaded shutoff valve, fixture supply, or equipment port. The slip end accepts standard 1/2-inch copper tubing for soldering, and the male NPT end threads directly into a female-threaded fitting, valve, or manifold. Its wrot construction means it is wrought from copper stock, producing a denser, more pressure-capable fitting than cast alternatives.
Designed as a standard OEM-style wrot copper adapter for use in residential, commercial, and industrial plumbing and refrigeration piping systems where a 1/2-inch copper solder connection transitions to a 1/2-inch male NPT threaded connection.
Installation should be performed by a licensed plumber or qualified refrigeration technician in accordance with applicable local codes, IPC, and ASME standards. Shut off the water supply or recover refrigerant and relieve system pressure before beginning any work. The slip end requires proper tube preparation, flux application, and lead-free solder per local potable water codes before applying heat. Hand-tighten the male NPT end into the female-threaded fitting and apply thread sealant appropriate for the service medium before final tightening with a wrench.
