The Toro TL-M50 Tri-Loc 1/2 in. MPT Male Adapter provides a fast, reliable connection between 1/2" male pipe threads and 16–18 mm dripline. Designed for irrigation professionals and DIY installers, the Tri-Loc system reduces installation time and prevents tubing mismatches across common dripline sizes.

  • Universal fit: Accepts 16, 17 and 18 mm outer-diameter dripline and hose, compatible with Toro Drip In® and DL2000™.
  • Secure connection: Barbed insert and ergonomic twist-off collar produce superior retention strength without tools.
  • 1/2" MPT thread: Standard male pipe thread for easy attachment to valves, manifolds, and fittings.
  • Reusable design: Twist-off collar allows fittings to be removed and reused during maintenance or reconfiguration.
  • Quick installation: Push tubing fully onto the barb, then tighten the collar by hand until snug for a reliable seal.
  • Contractor-friendly: One fitting covers three tubing sizes, reducing inventory and speeding repairs and system expansions.

The TL-M50 is molded from durable plastic suitable for routine landscape and garden drip systems. It’s an ideal choice when extending existing zones, repairing damaged lines, or building new low-pressure drip installations.
