DIG's most advanced drippers. Our PC drippers allow longer runs with equal flow from each dripper at any pressure between 10 and 55 PSI. They are self-cleaning, utilizing a silicone diaphragm which presses against the water passage as pressure and flow fluctuate to provide preset flow rates; when the pressure is below 10 PSI, the diaphragm is completely open, allowing particles to be washed through. PC drippers are very durable and can withstand harsh conditions. The drippers have a 1/4" barb inlet and are available in all our drip kits.
