Be sure of the outer diameter of your pipe and buy fittings that "fit".- If this O.D. 1/2 inch drip irrigation fittings are used in high outdoor temperature, the PE drip hose will expand and occasionally the water pressure will cause them to blow apart. We would recommend using hose clamps at the connection to avoid that problem.- The connector can be used to connect two hose ends of a 1/2" PE hose. For example, when connecting two PE hose reels, or even when repairing a damaged area, this connector provides a reliable and quick connection.
