The Barbed Female Combo Tee (Insert x Insert x FPT) is a specialized fitting designed to install a threaded sprinkler riser directly into a run of poly tubing. Featuring two barbed ends for a secure "insert" connection to your supply line and a Female Pipe Thread (FPT) outlet in the center, this tee eliminates the need for complex glued manifolds. To ensure a leak-proof system, all barbed connections must be secured with Hose Clamps.
These durable irrigation fittings are molded from high-impact Schedule 40 PVC, making them resistant to agricultural chemicals and UV degradation. They are the professional standard for adding overhead sprayers, shrubs, or pop-ups to a flexible poly pipe system.

Hose clamps are required for a secure fit.
Step 1: Prep the Riser
Wrap the threads of your riser or sprinkler with Thread Seal Tape. Screw it into the center threaded port of the tee. Hand tighten firmly.
Step 2: Cut the Line
Cut your poly tubing at the desired location for the sprinkler. Ensure the cut is clean and square.
Step 3: Insert Barbs
Slide a hose clamp over each end of the tubing. Insert the barbed ends of the tee into the tubing. Tip: If the pipe is cold, dipping the ends in warm water can make insertion easier.
Step 4: Clamp
Slide the clamps over the area where the tubing overlaps the barbs. Tighten the clamps securely with a nut driver or screwdriver.
