The MUELLER STREAMLINE 9096500 is a 611-series copper tee fitting used in residential and light commercial plumbing and HVAC refrigerant piping systems. It features a C x C x C (copper sweat) end configuration, accepting 3/8 inch nominal copper tubing on all three ports. The fitting is manufactured domestically from copper, making it suitable for potable water, hydronic, and refrigerant line applications where reliable brazed or soldered joints are required. Licensed plumbers and HVAC technicians routinely use this style of tee to branch copper supply lines during new construction and retrofit work.
This tee is suited for 3/8 inch nominal copper tubing installations in residential and light commercial settings. Typical applications include domestic hot and cold water distribution, baseboard heating supply and return branches, and refrigerant piping splits. The sweat-style end connections require flux and solder or brazing alloy, making this a standard fitting for any copper pipe rough-in or repair scenario.
Designed as an OEM-style replacement or new-install copper tee for 3/8 inch nominal copper tubing systems using C x C x C sweat connections.
Installation should be performed by a licensed plumber or HVAC technician in accordance with applicable local plumbing codes and IFGC requirements. Shut off and depressurize the water or refrigerant system and allow all components to cool fully before cutting into existing lines. Clean and flux all mating surfaces before applying heat to ensure a sound soldered or brazed joint. Avoid overheating the fitting body, as excessive heat can compromise joint integrity.
