Rain Bird Easy Fit compression coupling (model MDCFCOUP) makes connecting 1/2 in. polyethylene tubing faster and easier. Its low-force design reduces installation effort while providing a secure, leak-resistant connection for drip and xerigation systems.

  • Compatibility: Accepts 1/2 in. tubing with 0.630"–0.669" (16–17mm) outside diameter.
  • Material: UV‑resistant ABS plastic for long-term outdoor use.
  • Pressure Rating: 0–60 psi (0–4.1 bar).
  • Easy Fit System: Requires up to 50% less force to insert tubing; adapters swivel for simpler installs.
  • Use: Designed for above-ground drip and xerigation applications; not recommended for subsurface installations.
  • Installation: Push-fit compression coupling—no clamps or glue required for compatible tubing.

Compact, durable, and built for quick repairs or new layouts, this coupling reduces inventory needs by working across a range of 1/2 in. tubing sizes. Verify tubing outside diameter before installation to ensure proper fit.
