We have a really large selection of fittings for the Drip Tape we sell.
The tape slides over an inner extension and then an outer sleeve twists down over this sealing the tape onto the fitting. Works great and best of all it lets you easily remove the fitting at the end of the season. These fittings will work year after year for many years / seasons so they are a great investment.
Fits most 5/8" size tape products from 4 mil to 25 mil thickness.
