Reliable, UV-resistant reducing coupling designed to join Netafim 12mm Techline® EZ tubing to 17mm dripline. The one-piece, barbed construction creates a secure mechanical connection for low-volume drip irrigation applications, greenhouse systems, and landscape installations. Use for quick repairs, transitions between tubing sizes, or custom emitter layouts where a robust, puncture-free seal is required.

  • Compatible with Netafim Techline EZ 12mm and 17mm tubing.
  • One-piece, barbed design for a secure fit without clamps in typical installations.
  • Maximum recommended system pressure (without clamps): 50 PSI.
  • Acceptable hose IDs — 12mm: 0.426"; 17mm: 0.56"–0.60".
  • Durable UV-resistant plastic resists sun exposure and common irrigation chemicals.
  • Sold individually; bagged option available (25 per bag) for contractors and bulk installs.

Installation is straightforward: insert the smaller tubing onto the 12mm barb and the larger tubing onto the 17mm barb until fully seated. For higher-pressure systems or where extra security is desired, add a small hose clamp. Routine inspection is recommended at seasonal service intervals. See the manufacturer’s fittings and installation brochure for detailed guidance and compatibility notes.
