Constructed of molded ultraviolet-resistant high impact plastic, DIG's compression fittings with 3/4" female threads are used to start a drip irrigation system and connect the drip tubing or micro tubing to the water source. The fittings are available with 3/4" female hose thread or 3/4" pipe thread inlet and include a 60 mesh screen washer. DIG's drip irrigation adapters and tee fittings are installed by gardeners and professionals alike and available in two sizes and three configurations to start any type of drip irrigation system. Use the compression fittings with .700 OD and black inserts with DIG's 1/2" .700 OD drip tubing and the compression fittings with the .250 OD with DIG's 1/4" micro tubing. The compression fittings use a simple wrist action; the polyethylene drip tubing or micro tubing is "walked" into the compression side of the fittings for a very tight fit with no tools, glue, or clamps required.
