Video Transcript


The 700 series compression coupler from Irrigation Direct is used with drip irrigation connect two ends of half inch solid tubing or drip emitter tubing - or to make repairs when a goof plug will not work.

Look for the black compression rings at either end of the coupler. The black ring indicates 700 size

Installing a Drip Irrigation elbow is quick and easy.

To begin, simply cut your drip tubing with a pair of clippers or scissors. Make a straight cut across the pipe to ensure a tight fit. Insert your drip tubing into one end of the compression elbow and press inward, rocking the pipe and fitting back and forth. Use your thumb as a guide or score a mark on the tubing with your fingernail about 1 inch up from the end. Push until one inch of tubing is inserted into the fitting

When installing in cold weather, it helps to dip the tubing in warm water for a few minutes to soften the ends.

Compression fittings make a very tight seal and are difficult to pull apart. If you plan to remove your fittings or detach your drip tubing, use our Direct-Loc elbow

Direct-Loc fittings are perfect if you need to remove tubing for the winter.

Compression fittings come in several sizes and all are color coded for easy identification. Other common sizes are 620 and 710.

Green rings indicate 620 RainDrip tubing

Blue rings indicate 710 drip tubing

Drip irrigation is a watering method which delivers water to plants slowly and right where they need it at the roots. Where typical pop-up sprinklers spray water into the air and onto plants, drip irrigation systems combine flexible poly drip tubing and drip emitters or "drippers" to both conserve water and save money.

Drip irrigation systems are not affected by wind and will greatly reduce evaporation and runoff common with traditional irrigation systems. Drip irrigation is the perfect solution for raised vegetable garden beds, hanging baskets, and potted plants.
