Features & Benefits
DIG’s Universal Nut Lock™ Drip Fittings are used to connect drip tubing and drip line with dimensions from 1/2” to 5/8” or .620 OD to .710 OD. They can be used to connect two different sizes of drip tubing, providing a simple solution when there is no clear information about the drip tubing or drip line size used.
Used by both home gardeners and professionals, the Universal Nut Lock™ Drip Fittings are made of high-impact plastic for the connection of various sized drip irrigation tubing and drip line. Using a double barb, two pieces of drip line or drip tubing can be connected by inserting the fitting nuts over the drip tubing or drip line, then pushing the drip tubing or drip line over the barbed sides of the fitting, and finally threading the nuts over the drip tubing or drip line for a very tight grip.
