Constructed of molded ultraviolet-resistant, high-impact plastic, DIG’s Swivel 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. They are available with a 3/4″ female hose thread or 3/4″ pipe thread inlet and include a 60-mesh screen washer. The fittings are installed by gardeners and professionals, and are available in two sizes and three configurations to start any type of drip irrigation system. Use the .700 OD compression fittings with black inserts for 1/2″ .700 OD drip tubing and the .250 OD compression fittings for 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, glues or clamps required.

The customary method for starting a drip irrigation installation is to use 1/2” drip tubing as the main line to deliver water to the plant areas. In small systems such as those used on patios, the 1/4” micro tubing can also be used as the main line to deliver water to container pots and hanging baskets. These two sizes can also be used as the sub laterals to deliver the water from the main line directly to the plants. The most common drip fittings used to start the installation of a drip irrigation system with 1/2” drip tubing are the 3/4” FHT and FPT compression adapters and 3/4” FHT tee fittings.
Polyethylene drip tubing is available in coils of 50’, 100’, 200’, 500’ and 1000’. The size of the drip tubing varies by manufacturer, with each size displaying different flow characteristics but serving the same purpose – as a supply line for drip irrigation. To ensure problem-free operation, we recommend using DIG’s premium 1/2” drip tubing, made with 2%+ carbon black for extra resistance to ultraviolet rays and sized .600 ID x .700 OD, which is universally accepted as the standard sizing in commercial applications..
The 3/4” compression fittings are available in adapter and tee configurations to start the installation of any drip irrigation layout using 1/2” drip tubing or 1/4” micro tubing as the supply line. For any drip irrigation installation, we highly recommend installing a 25 PSI pressure regulator at the beginning of the system. The pressure regulator is used to lower the incoming pressure of the water to the system’s suggested operating pressure of 25 PSI, which is within the range of recommended pressures for drip irrigation or micro-sprinkler systems.
Hold the compression fitting in one hand and the drip tubing or micro tubing in the other and force the drip or micro tubing into the compression side of the fitting for about 1/2” by “walking” or “wiggling” the drip or micro tubing inside the fittings.
The 3/4″ swivel thread x .700 OD fittings with black inserts can be used with .690 OD, .700 OD and .710 OD drip tubing, and with our Brown PC drip line and include:
Model C37B 3/4″ FHT adapter: connects 1/4″ polyethylene micro tubing or vinyl micro tubing to the faucet or garden hose.
