1/2" .700 OD Compression End Cap with Flush Valve


1/2 in.  .700 OD Compression End Cap with Flush Valve
In Stock

The 1/2" compression x 3/4" automatic flush valve is used at the end of 1/2" drip tubing or drip line. The flush valve is used for automatic flushing of the drip line at the beginning and the end of each irrigation cycle. At the start of each irrigation cycle, when the pressure reaches 0.6 GPM, the flush valve closes and when the 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 .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.

This is the A148 flush valve with a 1/2 compression coupling. I replaced the original FHT cap with the A148 and it's worked well over several seasons. As long as you have some pitch in your mainline towards the end, this will drain much of the water when you shutoff the supply. I don't have access to a portable air compressor, so this saves me from flushing the lines before winter.

This did not work for me -- perhaps the pressure in my system wasn't high enough -- so the flush valve would not shut and the water leaked out. One out of 4 flush valves in my system worked fine.

This cutomer might be correct: these flush valves have minimum pressure requirements to operate normally.  If dynamic pressure on the system is too low (below 9 PSI) this valve will remain in "flush" mode.  Use pressure gauge on the end of the line (remove flush valve) to determine working pressures.

Installation for 1/2" Compression Fittings

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.

Note: For other size tubing use the fittings with black insert for DIG® (.700 OD),  blue insert for Toro® blue stripe tubing (.710 OD)and the fittings with green insert for Rain Drip® and Rain Bird®(.620 OD)
