You will match the outside diameter of the tubing to the compression fitting size as the tubing is pushed inside this fitting. Barbed Tubing FittingsĬompression Fittings are very economical but more difficult to use. Barbed fittings are not easily removable. Higher pressures may require a clamp placed over the tubing where the barbs are located. Match the inside diameter of tubing to the barb size as these push into the tubing and are held in place by the sharp barbs in most low pressure systems. Perma-Loc Drip Tape Fittingsīarbed Fittings sometimes called insert fittings are very economical and pretty simple to use. These work the same way as the perma-loc tubing fittings but have a slightly different barb and locking collar nut suitable for the thin wall design of drip tape. Perma-Loc Fittings are also available for use with the thin walled drip tape used in straight row crop applications. Here is a video showing how easy this is. The collar nut is simply turned back towards the center of the fitting exposing the barb then the tubing is slid over the barb and the collar nut is tighten back out over the tubing holding it securely in place. Perma-Loc Fittings are by far the most popular among DIY’ers, as they are durable, easy to use, removable, and reusable. Irrigation poly tubing sizes are not standardized so careful planning is necessary to match fitting sizes to tubing inside diameter and outside diameter. Several options for fittings are available for use with poly tubing. Poly tubing is flexible and easy to work with. Most often, drip irrigation operates at less than 30 PSI so LDPE (low density polyethylene) tubing can be used for water distribution from the valve out in most applications. Low pressure drip irrigation is becoming more popular as concern for water conservation increases. Additional information and tips on selecting fittings for drip irrigation can be found in our Fitting Buying Guide and Fitting Installation Tips. We will share a bit of information about a variety of fitting categories and uses followed by a list of some of the names of fitting styles to help you search for the correct fitting for your application. A simple backyard vegetable garden uses a simpler design than a larger commercial crop garden. A low pressure drip irrigation project uses different piping, so needs different fittings, than a higher pressure lawn irrigation system. Much of it depends on what your project is. We hope this will help clear things up so you can choose the right fitting the first time. Wow! There are so many options and so many different kinds it all the sudden gets confusing. Selecting the correct fitting for your particular irrigation project does not seem that difficult until you start searching the internet.
