Midland Industries 10189 Reducing Branch Tee Brass

Product Description

The MIDLAND INDUSTRIES 10189 is a forged brass reducing branch tee designed for SAE 45-degree flare hydraulic and fluid system connections. It joins three lines with a 5/8-inch male flared port on each of the two run ends and a 1/2-inch male flared port on the branch outlet. Thread specifications are 7/8-14 on the larger ports and 3/4-16 on the reduced branch. The fitting is rated to 650 psi and handles temperatures from -65 to 250 degrees F. Licensed plumbers, HVAC technicians, and hydraulic system installers typically work with this fitting in copper, brass, aluminum, and steel tubing applications.

This reducing branch tee is suited for residential and light commercial fluid systems where a single supply line must branch to a reduced-size outlet while maintaining full SAE 45-degree flare integrity. Its forged brass construction makes it appropriate for hydraulic tubing runs in HVAC refrigerant line sets, fuel systems, and hydraulic equipment that use compatible tubing materials. The 0.035-inch tube wall requirement and 0.69-inch body size make it a practical choice for tight routing in equipment panels and mechanical rooms.

Key Features

Compatibility

Designed for use with copper, brass, aluminum, and steel hydraulic tubing conforming to SAE 45-degree flare standards. Thread engagement is 7/8-14 on the 5/8-inch ports and 3/4-16 on the 1/2-inch branch port.

Installation Notes

Installation should be performed by a qualified technician familiar with hydraulic or refrigerant tubing systems. Depressurize and isolate the system completely before disassembling any fittings. Use an appropriately sized flare nut wrench to avoid rounding the fitting body; do not use pipe wrenches on flare fittings. Verify tube wall thickness meets the 0.035-inch minimum before flaring to ensure a leak-free seat.
