.450″ OD to .710″ OD Compression Fittings
Constructed of molded ultraviolet-resistant, high-impact plastic, DIG’s Compression Fittings are available to fit most sizes of polyethylene drip tubing and drip line from 1/2″ to 5/8″ in any drip irrigation installation. They are available in a variety of sizes and configurations with home gardeners and professionals using .700 OD compression fittings (black inserts) for 1/2″, .700 OD drip tubing, and .710 OD compression fittings (blue inserts) for 1/2″ .700 OD drip tubing and TORO®’s .710 OD blue strip drip tubing. The compression fittings use a simple wrist action; the polyethylene drip tubing is “walked” into the fittings for a very tight fit with no tools, glues or clamps required.

Demonstration Connecting 1/2" Compression Tee to .700 Poly Tubing
About
The customary method in drip irrigation installation is to use the 1/2″ drip tubing as the main lateral or the supply line to deliver water to the plant area. It also can be used as the sub lateral to deliver the water directly to the plants. The most common drip fittings used in the installation of drip irrigation are the compression fittings.
Polyethylene drip tubing is available in coils of 50′, 100′, 200′, 500′ and 1000′. DIG’s premium 1/2″ drip tubing is made in a range of different lengths. It is made with 2%+ carbon black for extra resistance to ultraviolet rays and is sized .600 ID x .700 OD which is universally accepted as the standard size. 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 with the .700 OD black compression fittings. In the event that you have an odd size of drip tubing, we offer reducing couplings and universal fittings to complete the project.
The compression fittings are available in configurations that include couplings, tees, elbows, PVC pipe to drip tubing connectors, ends, swivel adapters and swivel tees to start and complete the installation of any drip irrigation layout. 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.
Compression fitting installation:
Hold the compression fitting in one hand and the drip tubing in the other and force the drip tubing into the fitting for about 1/2″ to 3/4″ by “walking” or “wiggling” the drip tubing inside the fittings.
Drip fitting details and uses
The .700 OD fittings with black inserts can be used with .690 OD, .700 OD and .704 OD drip tubing, and with our Brown PC drip line. They include:
- Model C33 coupling: use to connect two pieces of polyethylene drip tubing
- Model C35 tee: allows for a three-way layout of polyethylene drip tubing
- Model C36 elbow: allows a 90° layout around corners for polyethylene drip tubing
- Model D48 coupling: use to connect polyethylene drip tubing into 1/2″ PVC pipe
- Model Q58 end cap: use to close the end of polyethylene drip tubing. The swivel cap can be removed when it is time to flush the line.
The .710 OD fittings with blue inserts can be used with .700 OD, .704 OD and .710 OD drip tubing. They include:
- Model C43 coupling: use to connect two pieces of polyethylene drip tubing
- Model C45 tee: allows for a three-way layout of polyethylene drip tubing
- Model C46 elbow: allows a 90° layout around corners for polyethylene drip tubing
- Model Q68 end cap: use to close the end of polyethylene drip tubing. The swivel cap can be removed when it is time to flush the line.
The reducing compression fittings with blue x black and green x black inserts can be used to connect two different sizes of drip tubing, .700 OD x .710 OD and .700 OD x .630 OD. They include:
- Model D50G reducing coupling: connects DIG’s .700 OD polyethylene drip tubing (black insert) to RAIN DRIP’s or RAIN BIRD’s .620/.630 OD polyethylene drip tubing (green insert)
- Model D50B reducing coupling: connects DIG’s .700 OD polyethylene drip tubing (black insert) to TORO’s .710 OD polyethylene drip tubing (blue insert)
