Rain Bird XFFCOUP 17mm barb insert coupling provides fast, secure connections for XF-series dripline. Redesigned self-holding barbs and a large center flange reduce insertion force so fittings install quickly and resist pullout.

  • Compatibility: Fits Rain Bird XF, XFD, and XFS series driplines and most 17 mm OD polyethylene tubing.
  • Secure fit: High-quality self-holding barbs and a positive tube stop prevent blowouts and maintain a leak-free seal.
  • Easy installation: Redesigned barb geometry reduces hand fatigue and installs over twice as fast; optional XF insertion tool speeds large installs.
  • Durable construction: Break-resistant plastic in a brown finish blends into landscapes and resists cracking under normal conditions.
  • Operating range: Rated for 0-50 psi (1.0-3.5 bar); clamps required if system pressure reaches 60 psi (4.1 bar).
  • Applications: Ideal for residential and commercial landscapes, parks, sports fields and retrofit kits where reliable drip connections are needed.

Sold individually; check ordering options for multi-packs. See the product sell sheet and technical specifications for installation guidance and dimensions.
