The Drip Depot Pressure Compensating Button Dripper with Barbed Outlet has a special no-leak design that enables the dripper to open at 5.5 PSI and close at 4 PSI. Dripper has 1/4" barb inlet and 1/8" outlet. Can be inserted into 1/4" microtube or directly into 1/2" poly tube by punching a hole into the 1/2 tubing and then inserting the dripper. Pressure compensating drippers have built-in diaphragms that react to pressure, assuring equal flow. Their vibration during operation prevents clogging. Each dripper allows the same flow between 10 and 55 PSI. Use for trees, shrubs and flowerbeds. Ideal for medium and heavy soils - flat ground, hillsides and uneven terrain. Pressure compensating drippers are our most advanced drippers. They are designed for long life under the harshest conditions.
Note: These are not "in-line" drippers. ie, you cannot "daisy-chain" them together.
