Marine Boat Seal Drain Plug

Problems This Product Solves

• Water Leakage at Drain Port: Precision threaded design creates a tight, watertight seal that prevents bilge water from seeping back in or leaking around the plug.
• Lost or Dropped Plugs: The anti-loss retention clip/tether keeps the plug permanently attached to the boat — no more searching for a missing plug before launch.
• Difficult Removal & Installation: Non-slip base and ergonomic grip allow easy one-hand tightening and removal, even with wet hands.
• Corrosion & Degradation: High-quality plastic construction resists saltwater corrosion, UV exposure, and temperature extremes for long service life.
• Incompatible Plug Sizes: Available in two shapes (Circular / Rhombus) and two sizes (Small / Large) to fit the widest range of standard marine drain openings.
