They are very easy to use and require no special tools. Perma-Loc fittings are available for both Tubing and Tape. The tubing connectors can be used on blank tubing as well as drip line.To Use: Simply twist the locking collar back towards the center of the fitting exposing the barb. Then push tubing or tape over barbed end. Next, hand-tighten locking nut over tubing or tape for a permanent secure fit.To Remove: Just loosen locking nut, pull tube off and re-use as needed.Perma-Loc fittings look similar to traditional flange and locking nut plumbing connections; however, in most cases, they work differently. Unlike a typical locking nut which comes off the fitting and slides over the tubing, a Perma-Loc locking nut is not removed from the fitting.
