Irritec Perma-Loc Tubing End Cap Flush Valve
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.
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.
