Power-Loc™ fittings are designed for secure and reliable connections with polyethylene irrigation tubing. Featuring a single-barb design with a threaded drive ring, they allow tubing to slide on easily and seat firmly against the positive stop, ensuring proper installation every time. Their low-effort, square-thread drive ring quickly locks the tubing in place without the need for tools. Engineered for durability, the fittings are manufactured from tough, non-corrosive plastic that resist chemicals and UV degradation.
