How to Clamp a Poly Pipe to a Plastic Barb Fitting

What You'll Need
Plastic barb fitting
2, Hose clamps
Rubber mallet

You can install plastic barb fittings into your existing pipe system without much effort, and in such a way that it will prevent breaks and leakages. You can use t-bands or elbows to split or extend your pipe, or even to repair breaks in your system to prevent leaks.

Step 1 - Heat the Pipe

Slide your hose clamps over the ends of the pipe that is going to be joined. Once these are in place, use your torch to heat the end of your piping. This will allow you to get your plastic barb to slide in a good distance, and create a water tight seal. 

Step 2 - Use the Mallet to Drive the Barb into the Pipe

Place your plastic barb over the pipe, and use your rubber mallet to drive it into place. The ribs on the barb will grip tightly to the inside of the heated pipe, and your pipe clamps will lock them into place.

Step 3 - Tighten the Clamps

Once the plastic barb is in place, simply slide the clamps over the ends and tighten them down. These are going to put outside pressure on the hose, pinning it to the barb. You can cut excess clamp material from the finished piece to prevent snagging and cuts from passing by the joint.
