A thickened PP plastic thru-hull drain tube for boats and yachts — drains accumulated water from bilge, baitwell, livewell, and motorwell to stabilize the vessel’s center of gravity and maintain safe handling.


🔺 Product Details

Key Features

  • Thickened PP Material – High-density polypropylene; impact-resistant, anti-oxidation, and corrosion-resistant for long-term saltwater use
  • Anti-Aging – UV-stable PP construction resists cracking and degradation in harsh marine environments
  • 360° Flange Nut Lock – Threaded flange nut rotates a full 360° for easy tightening from inside the hull; secure, leak-free fit
  • Two Sizes Available – 3/4" (18mm inner bore) and 1-1/4" (27mm inner bore); fits standard boat hull drain holes
  • Two Colors – White and Black; matches your deck or hull finish
  • Wide Application – Fits yacht, baitwell, livewell, motorwell, and general hull drainage

Problems Solved

  • Prevents water accumulation that causes vessel imbalance and handling issues
  • Replaces rusted metal or cracked plastic drain fittings that leak or seize
  • Eliminates difficult installation — 360° flange nut tightens from inside without special tools
  • Stops UV degradation failures common with low-grade plastic fittings
