About Perma-Loc Drip Irrigation Fittings:
Perma-Loc fittings and adapters are heavy duty reusable connectors for all your connection needs. Perma-Loc fittings require no special tools to connect to tubing or tape. Perma-Loc fittings can be used on blank tubing or 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 the barbed end. Next, hand-tighten the locking collar over the tubing or tape for a permanent, secure fit.
-
To Remove: Just loosen locking collar, 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.
A Perma-Loc Tubing Elbow is used to connect two pieces of the same size polyethylene tubing to achieve a 90° turn.
