Orbit Riser-Flex Spiral Barb Swing Fittings are compatible with Funny Pipe from Toro, as well as 1/2-in. swing pipe from Hydro-Rain, Rain Bird, and Hunter. These fittings are constructed from durable ABS. The spiral barb threads directly into black swing pipe, creating a watertight seal. We recommend Blu-Lock fittings and pipe for their superior speed of installation, flow, flexibility, and releasability. The 1/2-in. Blu-Lock x Spiral Barb adapter is the perfect way to transition from existing swing pipe to Blu-Lock. For non-constant pressure outdoor irrigation use with cold water only.
