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.

These Perma-Loc tubing x flush valve end caps are a one-way valve used for automatic flushing of the tubing at the beginning of each irrigation cycle. This low pressure valve allows water to flush out at system start-up with as little as 0.66 GPM (39.6 GPH ) flow required to close the valve. The valve opens at shutdown when system reaches 0.87 PSI .
