Description

The Drip Store’s compression fittings from DIG Corporation are constructed of molded ultraviolet-resistant high impact plastic and are available to fit most sizes of drip tubing and drip line from 1/2” to 5/8". Our compression drip fittings are available with 3/4” female threads or 3/4” male thread inlet and come in a wide range of configurations to meet all applications of drip irrigation systems.

 

The Drip Store's 1/2" compression fittings with .700 OD (black insert) are used in the installation of a drip irrigation system that uses .690 OD to .704 OD drip tubing and drip line.
To connect the drip tubing into the compression fitting, insert the .690 OD to .704 OD drip tubing into the compression side of the fitting, pushing and wiggling the tubing back and forth into the fitting. The 1/2" compression fitting side uses a simple wrist action and the drip tubing is "walked" into the fittings for a very tight fit, ensuring a quality watertight connection. No tools, glue or clamps are required.

 

Suggestion in connecting the 1/2" compression drip fittings. To install the 1/2" compression fittings, cut the drip tubing with a hand pruner, being careful to keep dirt from entering the line. Hold the compression fitting in one hand and the drip tubing in the other and force the drip tubing into the fitting by wiggling it from side to side. Make sure that the drip tubing is pushed into the compression fitting for about 1/2 to 5/8 of an inch for a very tight fit. No glue or clamps are required.

instruction

The air relief valve connection is normally located near the pressure regulator assembly as this is often the highest point in the drip system or the center of the line. It is important to install the air relief valve at the highest point of the system layout to allow it to work correctly.
