Midland Industries 18291 Brass Male Branch Tee Compression

Product Description

The MIDLAND INDUSTRIES 18291 is a forged brass male branch tee designed for compression-style tube connections in fluid and gas line applications. It features two 1/4-inch tube OD ports and one 1/8-inch male NPTF port, with a 7/16-24 x 1/8-27 thread configuration. Rated to 300 psi and suitable for temperatures ranging from -65 to 250 degrees F, this fitting handles demanding service conditions. The forged brass construction provides corrosion resistance and durability in both wet and dry service environments. Plumbers, HVAC technicians, and pneumatic system installers commonly use this fitting to branch a compressed-air, refrigerant, or fluid line off a main tube run.

This branch tee is intended for use with copper, aluminum, and thermoplastic tubing in residential and light commercial systems. It is well suited for pneumatic controls, low-pressure gas distribution, and instrumentation lines where a compact tee connection point is required. The 0.36-inch body size keeps the fitting footprint small in tight panel or cabinet installations where clearance is limited.

Installation Notes

This fitting is typically installed by licensed plumbers, HVAC technicians, or pneumatic system mechanics. Shut off and depressurize the line completely before disassembly or installation. Ensure tubing ends are cut square and deburred before seating in the compression ports to prevent leaks. Verify that the NPTF thread engagement meets applicable IPC or system manufacturer requirements before returning the line to service.
