The 1/2" compression x 3/4" automatic flush valve is used at the end of the 1/2" drip tubing or drip line. The flush valve is used for automatic flushing of the drip line at the beginning and the ends of each irrigation cycle. At the start of each irrigation cycle, when reaching 0.6 GPM, the flush valve closes, and when pressure drops below 1 PSI the valve opens.
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 .710 OD (blue insert) are used in the installation of a drip irrigation system that uses .704 OD to .710 OD drip tubing and drip line.
To connect the drip tubing into the compression fitting, insert the .704 OD to .710 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.

To connect the 1/2" drip tubing, cut the drip tubing with a hand pruner, being careful to keep dirt from entering the drip tubing. Hold the fitting in one hand and the drip tubing in the other and force the tubing into the fitting while wiggling the drip tubing from side to side. "Walk" the drip tubing into the fitting until about 1/2" to 3/4" of the drip tubing is inside the fitting.
