Universal Nut-Lock Fittings

DIG’s Universal Nut-Lock Drip Fittings are used to connect drip tubing and dripline with dimensions from 1/2” to 5/8” or .530 ID, .600 ID and .620 ID. 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 dripline 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 dripline. Using a double barb, two pieces of dripline or drip tubing can be connected by inserting the fitting nuts over the drip tubing or dripline, then pushing the drip tubing or dripline over the barbed sides of the fitting, and finally threading the nuts over the drip tubing or dripline for a very tight grip.

About

The Universal Nut-Lock Drip Fittings provide a simple, low-cost method for the installation of dripline and drip tubing. Using the double barbed fittings, dripline or drip tubing is pushed over the barbs for a very tight fit.

The Universal Nut-Lock drip fittings are made from high-impact plastic material to withstand any installation application. They are available to fit various sizes of drip tubing and dripline from 1/2” to 5/8”, providing a simple solution when connecting two ends of drip irrigation tubing or dripline that are not the same size. The fittings use an assembly configuration that includes a barb, a nut with female thread and a male thread adapter to connect different sizes of drip tubing and dripline. They hold the drip tubing or dripline from the inside with the barb and from the outside with a compression-type threaded nut.

To connect any two sizes of poly drip tubing with .530 ID, .600 ID or .620 ID, use the following steps:

Installation Steps
