Use this 1/2-in coupling to connect or repair pieces of 1/2-in poly tubing
Typically use this 1/2-in coupling to add on and expand your micro-spray and drip irrigation system or to repair a cut in the 1/2-in poly tubing
To attach the 1/2-in poly tubing first push the collar back to expose the barb with a built in O-ring
Push and wiggle the 1/2-in poly onto the fitting and under the collar until snug
While holding the tubing with 1 hand turn the ears of the collar in a left counter-clockwise motion to tightened and lock onto the 1/2-in poly tubing
Repeat these steps for both sides of this coupling
This fitting can be uninstalled easily by unthreading the collar in a clockwise motion then by pulling off the 1/2-in poly
If you find it difficult to get the 1/2-in poly tubing onto the fitting, use a little olive oil or vegetable oil by wiping it on the inside of the wall of 1/2-in poly then push in the fittings
