Universal Nut Lock™ Fittings

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.

About

The Universal Nut Lock™ Drip Fittings provide a simple, low-cost method for the installation of drip line and drip tubing. Using the double barbed fittings, drip line 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 drip line from 1/2” to 5/8”, providing a simple solution when connecting two ends of drip irrigation tubing or drip line 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 drip line. They hold the drip tubing or drip line 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 .620 OD to .710 OD, use the following steps:

  1. Unthread the nut and slide the nut into the drip tubing or drip line end.
  2. Push the drip tubing or drip line over the barb.
  3. Thread the nut to secure the drip tubing or drip line.
