About Drip Depot Perma-Loc Drip Irrigation Fittings:
Perma-Loc fittings are heavy duty reusable connectors, adapters and fittings for all your connection needs. 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 push tubing or tape over barbed end, then 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 usually not removed from the fitting. The exception to this rule are some of the larger 3/4" and above tubing fittings. Select a video from above to see how the Perma-Loc drip irrigation tubing and tape fittings work.
