Equal Compression Tee for PE Irrigation Pipe

An equal compression tee creates a perpendicular branch from a polyethylene irrigation supply line. Two opposing connections continue the main run while the third connection turns out to the side. The blue nuts and black T-shaped body distinguish it from an elbow or straight connector. Use the equal tee when the main and branch use the same pipe diameter.

Plan the branch route

Set out the main run and side branch before cutting any pipe. Keep all three pipe ends aligned with their respective sockets and provide support where the branch changes direction. A tee adds a water path, but the flow available to each downstream zone still depends on the supply, pipe lengths and connected outlets.

Match the pipe before assembly

Compression fitting sizes refer to the pipe connection diameter. Check the actual outside diameter, pipe material and wall specification rather than relying on an inside-diameter measurement. The selected option must match every connected pipe. Confirm the permitted pressure and temperature for your complete system before installation; the weakest component determines the usable operating limit.

Prepare and test the connection

Turn off the water and release pressure before working on the line. Cut the pipe square, remove loose debris and check the end for scratches or distortion. Follow the fitting assembly instructions for insertion depth, any required pipe support and tightening. Keep the sealing surfaces clean and avoid forcing a misaligned pipe into the socket. Bring the zone up to pressure gradually, inspect every connection and resolve any leakage before covering the pipe.

Choose the right fitting shape

Check the route and number of outlets as well as the size. Leave the joint accessible during the initial test and provide space for later inspection. A correctly selected fitting should suit the planned layout without twisting the pipe or putting unnecessary strain on the connection.
