Also called a coupling, it joins fitings and pipe of like size together. Couplers may be slip, threaded, barbed or compression or combination thereof.
Connecting unlike items is called “adapting”. See Adapter.
Fittings used to connect lengths of 1/2" and 3/4" drip tubing. The tubing is simply inserted into the compression fitting. Glue is not required. See also Poly Pipe.
Drip irrigation is a watering method which delivers water to plants slowly at the roots. It is also known as trickle or micro-irrigation. 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 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 beds, vegetable gardens, and potted plants. See also Emitter, Barbed Fitting, and Poly Pipe.

Also called a dripper, an emitter distributes water droplets at a specified flow rate when used as part of a drip irrigation system. Drippers come in a variety sizes, styles, and flow rates. They have barbed or threaded bases. Barbed ends are either poked into 1/2" drip tubing or inserted into the end of 1/4" tubing. Threaded bases are screwed into micro tubing stakes and risers.
Drip Emitter Tubing comes with emitters pre-inserted in the tubing. It can be purchased in both 1/2" and 1/4" sizes with drippers spaced from 6 inch to 3 foot intervals.
Inline Emitters are use to create custom emitter tubing when used with 1/4" solid drip tubing.
Pressure Compensating Emitters distribute a consistent flow rate regardless of fluctuations in pressure.
Non-Pressure-Compensating Emitters will distribute varying flow rates as pressure fluctuates with elevation changes.
Staked Emitters sit on a spike and may distribute water in a spray or stream.
Multi-Outlet Emitters can be installed onto existing sprinkler rises as part of a sprinkler retrofit project. 1/4" tubing is installed on the emitter outlets and run to individual plants.

The common name for parts that connects irrigation parts and pipe. These include elbows, tees, couplers, crosses, male adapters, female adapters, swivel adapters, control valves, reducers, bushings, street elbows. They may be threaded, slip, barbed, compression, or a combination thereof.
A filter contains a screen that is designed to remove particles from irrigation systems. Filters are critical components in a drip irrigation system. Drip emitters may clog if proper filtration is not provided. Typical screen mesh is 120, 150, and 200 mesh. The greater the number, the smaller the openings in the screen. 200 mesh is recommended for foggers (misters).
A device that lowers water pressure on the downstream side and maintains a constant operating pressure. Regulators are commonly used in drip irrigation applications as drip tubing and fittings are usually rated to operate at pressures lower than most household water systems. Always install a regulator after a valve and filter. They are not designed to be operated under constant pressure.
Pressure Compensating Emitters. The output will not vary with changes in elevation and pressure. Pressure compensating drippers deliver the stated gph (gallons per hour) even if pressures range from 10-50 psi. These pressure compensating drippers are best used with elevation changes. Pressure compensating drippers are self-flushing to reduce clogging. See also Emitter, Non-Pressure-Compensating.
Non-Pressure-Compensating Emitters. The output will vary with changes in elevation and pressure. These non-pressure compensating drippers are best used where the watering zone is level. Some non-pressure-compensating drippers are used with gravity-fed drip systems. They operate best at lower pressures. Recommended Pressure for most non-p-c emitters: 15-20 psi.
