Drip Irrigation

Compression fittings are among the most common connection style fittings used in drip irrigation systems to connect sections of either 1/2″ or 3/4″ solid drip irrigation tubing or dripperline. Compression fittings have an internal compression ring that squeezes the outside diameter of the tubing as it is inserted into the fitting. The sharp edge of the ring bites into the soft tubing to prevent the tubing from blowing off the fitting and also creates a water tight seal. Compression fittings are more of a permanent connection and are not recommended for reuse. Once the tubing is inserted into the fitting it is very hard to remove the tubing. The compression fittings are available to fit a range of tubing from ½” to ¾” and all are color coded to indicate the appropriate tubing outside diameter they fit. The range of compression fittings includes couplings, tees, elbows, male thread adapters, spigot adapters and end plugs.

Quick Lock fittings are becoming more popular as the distribution tubing can more easily be removed and the fitting can be re-used. They are similar to the insert fitting but have an external locking nut which needs to be tightened to get a secure connection. Simply loosen the nut if the tubing needs to be removed. Quick-Lock fittings are available as couplings, tees, elbows, plugs and hose adapters. Available for 3 different tubing sizes ranging from 1/2” to 3/4”.

Insert fittings, which are also known as barbed fittings, are used to connect brown 17 mm dripperline. These fittings are manufactured from an engineering grade plastic and because of the sharp barbs, will make a secure and watertight fit. These are available in various configurations including couplings, tees, elbows and male threaded adapters. Simply place the end of the dripperline over the barbed fitting and press inward, gently rocking the tubing on to the barb.
