The RAIN BIRD x36279 is a barbed tee female adapter fitting designed for use with Rain Bird XF Series Dripline irrigation systems. This fitting features a 17mm barb inlet, a 3/4-inch FPT (female pipe thread) center connection, and a 17mm barb outlet, allowing technicians to branch a dripline run while connecting directly to a threaded supply line or zone valve. The x36279 is engineered for fast installation, with a redesigned barb geometry that allows it to be installed more than twice as fast as conventional barbed fittings. Irrigation contractors and landscape professionals are the primary installers of this component.
This fitting is compatible with all Rain Bird XF Series Dripline products, including XFD Dripline and XFS Subsurface Dripline. It is well suited for residential and commercial drip irrigation zones where a tee connection to a threaded port is needed mid-run. Typical applications include in-line branching from a main dripline loop to a threaded manifold, valve, or filter assembly. The 17mm barb sizing matches standard XF Series tubing dimensions, keeping the installation within a consistent fitting ecosystem.
Designed for use with all Rain Bird XF Series Dripline, including XFD Dripline and XFS Subsurface Dripline.
Installation is typically performed by licensed irrigation contractors or landscape irrigation technicians. Shut off the water supply and relieve system pressure before cutting into an existing dripline run. Push barbed ends fully into XF Series tubing until the tubing seats against the fitting collar, and hand-tighten the FPT connection with appropriate thread sealant per local plumbing code requirements. Avoid using pipe wrenches or excessive torque on plastic fittings, which can crack the fitting body.
