Green Leaf Tt 12-18 Nylon Pipe Tee 1/2 X 1/8 in Fipt

Product Description

The GREEN LEAF TT 12-18 is a nylon plastic pipe tee fitting with an integrated gauge port, designed for low-pressure fluid and pneumatic piping applications. The fitting connects at 1/2-inch run ports and reduces to a 1/8-inch gauge port, with all three connections threaded FIPT for standard NPT male threaded pipe or fittings. Constructed from white nylon, this tee offers good chemical resistance and is lightweight compared to brass or steel alternatives. It is typically installed by plumbers, HVAC technicians, or pneumatic system technicians requiring a branch or gauge tap in a threaded plastic piping run.

This fitting is suited for residential and light commercial applications where a pressure gauge port or instrument tap is needed in a 1/2-inch threaded line. Common install scenarios include pneumatic control lines, water distribution branches, compressed air manifolds, and HVAC sensing line taps. The 1/8-inch FIPT gauge port accommodates standard pressure gauge fittings and instrumentation ports. Nylon construction makes this tee appropriate for systems where metal corrosion or weight is a concern.

Key Features

• Integrated gauge port allows instrument or sensor tap without additional fittings
• All-FIPT end connections accept standard NPT male threaded pipe and fittings
• 1/2-inch run size with 1/8-inch branch port for gauge or instrument connection
• Nylon construction resists corrosion and reduces overall assembly weight
• White finish for easy identification in mixed-material piping systems

Compatibility

Designed as an OEM-style threaded tee replacement or new-installation fitting for 1/2-inch FIPT threaded piping systems requiring a 1/8-inch gauge or instrument port.

Installation Notes

Installation is performed by a licensed plumber or qualified HVAC or pneumatic technician. Shut off and depressurize the line completely before disassembly or fitting installation. Apply thread sealant tape or liquid sealant rated for the media and pressure range to all male NPT threads before assembly. Do not overtighten nylon fittings; hand-tight plus one to two turns with a wrench is typical to avoid cracking the fitting body.
