Universal NUTLOC™ Fittings
DIG’s Universal NUTLOC™ Drip Fittings with brown or black nuts connect multiple blank drip tubing or dripline sizes ranging from 1/2” to 5/8” in size (16 to 18 mm). The NUTLOC™ fittings are reusable, heavy-duty, drip irrigation fittings that provide a practical solution when there is uncertainty about the precise size of the drip tubing or dripline installed or repaired. The NUTLOC™ fittings utilize a body with a barbed connection and a locking nut to ensure a secure, tight, and fast connection between separate pieces or varying sizes of drip tubing or dripline and are available in a range of configurations for residential, commercial, and agricultural applications.

English About
The Universal NUTLOC™ drip Fittings provide a simple, low-cost method for the installation of dripline and drip tubing.
The Universal NUTLOC™ 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 a stepped barb body, and a nut with female thread 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 of the 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
To connect the drip tubing or dripline, rotate the locking nut all the way backward or counterclockwise to the end, exposing the barb.
Insert the drip tubing or dripline entirely over the barb; wiggling it back and forth may help (use with any size between (.520 ID to .620 ID) or (.620 OD to .710 OD).
Screw the nut over the drip tubing, turning the nut forward or clockwise and tighten, locking the drip tubing in place. Repeat the steps for the other side.
The NUTLOC™ fittings can be reused by rotating the locking nut backward or counterclockwise and pulling the drip tubing out of the barb; wiggling it back and forth can help.
