The MUELLER STREAMLINE ADP00322 is a wrot copper adapter fitting designed to transition between a 0.88 inch copper sweat connection and a 0.75 inch female pipe thread (FPT) connection. This fitting is used to join copper tubing to threaded pipe or threaded components within plumbing, HVAC, and mechanical piping systems. Wrot copper construction provides reliable performance in pressure applications and is compatible with standard soldering and brazing procedures. The compact profile measures 1.61 inches in length and 1.19 inches in width, making it suitable for tight installation spaces. Licensed plumbers and HVAC mechanics are the primary installers of this fitting.
This adapter is appropriate for residential and light commercial plumbing and HVAC applications where copper tubing must connect to a female-threaded component such as a valve body, manifold, or fixture fitting. The C x FPT configuration makes it a common choice when transitioning from a soldered copper run to a threaded equipment connection. It is sold in minimum quantities of 25 units per order, which suits contractors and supply houses stocking for ongoing service work.
Designed as an OEM-style wrot copper adapter for use in standard residential and commercial copper plumbing and HVAC piping systems requiring a sweat-to-female-thread transition at 0.88 inch C x 0.75 inch FPT dimensions.
Installation of this fitting should be performed by a licensed plumber or qualified HVAC mechanic in accordance with applicable local plumbing codes and IAPMO or IPC standards. Shut off and depressurize the water or refrigerant system and ensure all moisture is removed from the pipe before soldering or brazing. Use appropriate flux and lead-free solder or an approved brazing alloy for the application. Apply thread sealant or PTFE tape to the female pipe threads before connecting the threaded component.
