Product Description

Perma-Loc Tubing Reducing Tee

These Perma-Loc fitting will convert Male Pipe Thread (MPT) to polyethylene tubing with an inline valve where on/off functionality is needed. Typically used to connect poly tubing to PVC fittings.

Special Note:  The 3/4" MPT x 3/4" Perma-Loc fitting (item #1525) works differently than other Perma-Loc fittings.  With this fitting you must first remove the locking nut from the fitting and slide it over the tubing.  Then, connect the tubing and reattach the locking nut.  In other words, this fitting works like traditional flange and locking nut plumbing fittings.

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.
