Restore reliable rain sensing without replacing your entire unit. The genuine Hunter 440200 Mini‑Clik cap & spindle assembly is the OEM repair kit that replaces worn hygroscopic discs and the spindle mechanism so a Mini‑Clik rain sensor resumes accurate on/off performance after rainfall.

  • Genuine Hunter replacement: Factory part designed specifically for Mini‑Clik rain sensors to ensure correct fit and long-term performance.
  • Complete cap & spindle assembly: Includes the top cap, spindle mechanism and fresh hygroscopic (cellulose) discs that react to moisture for accurate detection.
  • Restores sensor function: Replacing worn or contaminated disks fixes common failures—sensor not switching off after rain or false triggering when dry.
  • Easy installation: Twist-on/twist-off replacement that installs quickly without special tools; suitable for routine field repair and maintenance.
  • Cost-effective repair: Repair the existing Mini‑Clik sensor for a fraction of the cost of a full sensor replacement.
