Product Description

About Drip Depot Perma-Loc Drip Irrigation Fittings:

Perma-Loc fittings and adapters are heavy duty reusable connectors 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 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.

3/8" Perma-Loc 500 Series Fittings

We carry 3/8" Perma-Loc 500 Series fittings to convert smaller .520"  poly tubing to our 1/2" (or larger) tubing. The most common manufacturers of this type of tubing are:

RainDrip .520" ID (Inside Diameter)

RainBird .520" ID (Inside Diameter)

If you have an existing drip irrigation system with this size of tubing and you wish to expand it using Drip Depot poly tubing, you can use one or more of these adapters to make the different size tubings compatible.
