DIG's 17mm Barbed Fittings are precision-engineered to create secure, leak-free connections in drip irrigation systems using tubing with .570" to .600" ID, inner diameter. The double-barb design ensures a tight push-fit without the need for clamps, glue, or special tools—making them ideal for both professionals and DIY homeowners. Each fitting is made from UV-protected, high-impact polyacetal to withstand outdoor exposure, direct sunlight, and typical landscape chemicals. These fittings are available in a full range of configurations including connectors, tees, elbows, crosses, and MPT adapters to suit any system layout or repair. Recommended for use with DIG Excel PC Dripline and compatible brands, these fittings are trusted in residential landscapes, commercial installations, community gardens, and agricultural drip systems.
