Netafim 3/4in Insert Coupling with Rings
Supply pipe and heavy wall dripline both get cut, extended and rerouted over the life of a system. This straight insert fitting joins two pieces end to end so the run carries on as one line. Each half of the coupling carries a series of raised rings. Those rings are the barb, and each one bites into the inside of the pipe as it slides on. Several rings in a row give the joint more grip than a single ridge. Its brown color and part number match the 25 mm barb coupling in Netafim's connector catalog. Netafim lists that size for pipe with a 22 mm inside diameter and a 1.5 mm wall. Netafim describes the barb connector body as a UV and chemical resistant polymer. That matters on exposed runs and in lines that carry fertilizer. The fitting is a single molded piece with no nuts, sleeves or loose seals. Installation takes a sharp cutter and hand pressure, nothing more. A bag of 100 covers a full season of repairs and new lateral work across a large site.
Making a Barbed Pipe Coupling Hold
Turn the zone off and drain the pressure before cutting the line. Cut out any damaged section and square both pipe ends. A clean, straight cut lets the pipe seat evenly over all the rings. Check the pipe size against the fitting before pushing it on. Warm stiff pipe in the sun or in warm water so it stretches over the rings more easily. Push one pipe end onto the coupling with a slight twisting motion until it covers every ring. Repeat on the other side so both pipes meet near the middle. Do not use oil or soap on the barbs. A dry fit grips better. Turn the zone on slowly and watch both joints at working pressure. A small leak usually means the pipe did not slide fully over the last ring. On buried or exposed pipe, keep the joint straight and out of tension so the pipe does not pull back off. Flush the line after a repair to clear out soil and pipe shavings. Store spare couplings in their bag, away from sun, until they are needed.
