The JMF COMPANY 2510520209800 is a wrot copper adapter fitting designed to transition from a copper sweat (C) end to a female threaded (FPT) connection. Manufactured from C12200 copper alloy and produced to ASTM B75 material specifications, this adapter is built for reliable, leak-tight performance in demanding piping systems. At 1-1/4 inches on both ends, it suits standard pipe runs without reduction. The wrot construction process produces a dense, strong fitting that holds up to the pressure and temperature conditions common in plumbing and refrigeration lines. Licensed plumbers and refrigeration technicians are the primary installers for this type of fitting.
This adapter is suited for commercial, residential, and industrial applications across plumbing and refrigeration systems. The copper-to-female-thread transition is a common configuration when connecting copper tubing runs to threaded valves, manifolds, or equipment ports. The refrigeration outer diameter measures 1-3/8 inches on the sweat side and 1-1/4 inches on the threaded side, making it appropriate for refrigeration line sets where these dimensions are required. It conforms to ASME/ANSI B16.22 and MSS SP-104 standards, ensuring dimensional and performance consistency with other code-compliant fittings in the system.
Designed for use in plumbing and refrigeration systems requiring a 1-1/4 inches copper sweat to 1-1/4 inches female threaded adapter, conforming to ASME/ANSI B16.22 and MSS SP-104 dimensional standards.
Installation should be performed by a licensed plumber or refrigeration technician in accordance with applicable local codes, IPC, and IFGC requirements where relevant. Shut off the water supply or recover refrigerant and depressurize the system fully before cutting into any line. The sweat end requires proper flux application and silver or lead-free solder compatible with potable water or refrigerant service as applicable. Allow the joint to cool completely before pressurizing the system and checking for leaks.
