How to Protect Trees and Shrubs: Winter Climate Tips
Jan 29th 2026
The 1/2" Compression Elbow is the standard solution for creating sharp 90-degree turns in your drip irrigation system. Designed to connect two pieces of 1/2" poly tubing, this fitting prevents the "kinking" that often occurs when bending tubing around raised beds, corners, or walkways.
As one of our most essential irrigation fittings, the compression elbow utilizes a simple friction-fit design. An internal ring grips the tubing tightly once inserted, creating a permanent, leak-proof seal without the need for glues or clamps. It is an economical choice for permanent installations where reconfigurability is not required.

Install your elbows securely with the "Rock and Push" method.
Step 1: Cut the Tubing
Use a pipe cutter or shears to make a clean, square cut on your 1/2" poly tubing where you need the turn.
Step 2: Warm the Ends (Optional)
If the weather is cold, dip the end of the tubing in warm water or let it sit in the sun. This softens the plastic and makes insertion easier.
Step 3: Push and Rock
Insert the tubing into one end of the elbow. Apply force while "rocking" the tubing back and forth (up and down) to work it past the internal compression ring. You should feel it slide in about 1/2" to 3/4" deep.
Step 4: Repeat
Repeat the process for the other side of the elbow to complete the 90-degree turn.
Ensure you have the right size:
