The GREEN LEAF TT 34-18 is a nylon plastic pipe tee fitting designed for low-pressure fluid and air distribution systems. This tee includes an integrated gauge port, making it suitable for inline pressure monitoring without adding a separate fitting. Constructed from white nylon, the fitting offers corrosion resistance and light weight compared to metal alternatives. All three run connections and the gauge port use female iron pipe thread (FIPT) end connections at 3/4 inch and 1/8 inch sizes respectively. Licensed plumbers and HVAC technicians install this type of fitting in water supply, compressed air, and fluid handling lines.
This fitting is used in residential and light commercial plumbing, irrigation, pneumatic systems, and HVAC condensate or water distribution lines where a tee connection with an accessible gauge port is required. The 3/4-inch run connections handle standard branch flow, while the 1/8-inch gauge port accommodates common pressure gauge or sensor fittings. Its nylon construction makes it well suited for corrosive or moisture-heavy environments where metal fittings may degrade over time.
Designed as an OEM-style replacement or direct-install fitting for 3/4-inch FIPT threaded pipe systems requiring an inline tee with a 1/8-inch gauge port connection.
This fitting is installed by licensed plumbers or qualified HVAC technicians. Shut off and depressurize the system fully before removing or installing any threaded fittings. Apply appropriate thread sealant tape or compound to male threads before assembly and hand-tighten before using a wrench to avoid overtightening, which can crack nylon fittings. Follow applicable IPC or local plumbing codes for thread sealing and pressure ratings on the connected system.
