Insert or Barbed Fittings
Insert fittings have been around for a long time, are most familiar and easy to find. They work but have quite a few disadvantages. Difficult to install and take out, they are typically not reused. They also normally require clamps which increase the cost in both dollars and time. -
Compression Fittings
Typical drip compression fittings don't require clamps but become almost impossible to take out and reuse. An advantage to these is that they go on the outside of the supply line so they don't decrease the flow or PSI like insert fittings. -
Threaded Fittings
Threaded fittings have male or female threads so you can screw them into other fittings or components. They are often used to connect to faucets, filters, pressure regulators, or other components in your irrigation system. -
Quick Connect Fittings
Quick connect fittings provide a convenient and easy way to connect and disconnect tubing or drip lines. They normally have a push-and-lock mechanism that allows for quick installation and removal without the need for tools. Some automatically shut off the water when disconnected from either one or both sides. -
Lateral Line Fittings
Lateral line fittings are specifically designed to connect the main water supply line to the drip lines or tubing that distribute water to individual plants. These fittings ensure a secure and leak-free connection between the main line and the lateral lines. Layflat fittings are a good example. -
PVC Fittings
PVC fittings give solid, durable, and leak-free connections but require glue. That creates more of a safety concern, takes more time, and means you can't reuse them. -
Perma-Loc fittings
Perma-loc fittings solve many of the problems and disadvantages of the other types. Unlike insert fittings, they are easy to install and don't require clamps. Unlike most compression fittings, you can easily reuse them. Unlike threaded fittings, you don't need tools or even Teflon tape. Because they are so quick and easy to install, they can save a huge amount of labor and time. The elimination of threading, soldering, or gluing reduces labor costs and minimizes the chances for leaks, and reduces the need to buy new fittings. They also make repairs and system design changes much easier.
The specific fittings you'll need will depend on the design and requirements of your particular system, your budget, and availability.
