The Barbed Reducing Tee is a specialized insert fitting designed to split a main irrigation line while simultaneously reducing the tubing size for the new branch. Whether you are running a 3/4" header and want to feed a 1/2" garden bed, or stepping down from a 1" agricultural line, this fitting eliminates the need for multiple couplers and bushings. It allows you to create efficient, streamlined layouts using standard irrigation fittings and Polyethylene tubing.
Constructed from durable Schedule 40 PVC, these tees feature aggressive multi-ridged barbs on all three connection points (Run x Run x Branch). This ensures a secure, high-pressure grip that resists pull-out. Because these are insert fittings, they must be secured with stainless steel Hose Clamps to guarantee a leak-proof seal under constant water pressure.

Install your reducing tee correctly to ensure a leak-proof junction.
Step 1: Prep the Tubing
Cut your main line where the tee will be installed, and prepare your branch line. Ensure all cuts are square. For larger tubing, dip the ends in hot water to soften them for easier insertion.
Step 2: Position the Clamps
Slide a stainless steel Hose Clamp onto all three sections of tubing before inserting the fitting.
Step 3: Insert the Tee
Push the barbed ends firmly into the tubing. Ensure you match the correct tubing size to the correct port on the reducing tee (e.g., larger tubing on the run, smaller tubing on the branch).
Step 4: Secure the Connection
Slide the clamps into position over the barbs (do not clamp at the very edge). Tighten all three clamps firmly with a nut driver.
