Review on Tailonz Pneumatic Plastic Connect Fittings by Brett Kolpack

These parts work very well. As long as you install them correctly, they won't leak. However, you must be sure that you install them correctly. Make sure the tubing is cut at a 90° angle. Whenever you insert the tube, keep pushing until you feel something like a bulge. Maybe one day you'll hear it when all is quiet. This is the end of the hose that is fully included. Caution is also required when pushing through a stretched hose. If the tube is inserted at an angle, either by weight or tension, the teeth will bend and the tube cannot be removed once installed. It may well not flow, but the hose needs to be cut. You want to remove it. Otherwise, this is a good product that serves its purpose well.
