BULK 100 PACK. Use this 1/2-in Coupling to connect or repair pieces of 1/2-in Poly Tubing (MLT-25), (MLT-71), (MLT-72) or 1/2-in In-Line Drip Tubing (MLD-HDT100).
Typically use this 1/2-in Poly 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.
Next, push and wiggle the 1/2-in Poly Tubing onto the fitting and under the collar until snug.
Then, while holding the tubing with 1 hand, turn the ears of the collar in a left counterclockwise motion to tighten 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 Tubing.
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.
