Engineered for strong Deck Dryness

Upgrade your vessel's drainage with the Airow Marine Self-Bailing Scupper Valve. Constructed from high-impact, UV-stabilized polycarbonate, this valve features a precision-engineered neutral buoyancy polyethylene ball that reacts instantly to water pressure differentials. The enlarged exit path is hydrodynamically optimized to deliver 70% faster drainage than standard scupper units, helping support your deck stays clear in heavy chop.

Technical Superiority & Material Science

  • Automatic Anti-Reflux: The intelligent ball mechanism seals immediately against external wave pressure, preventing backwash into the cockpit.
  • Marine-Grade Durability: Featuring a PVC sealing gasket and corrosion-resistant fasteners, this unit is built for continuous saltwater exposure without deformation.
  • Universal Retrofit: Designed to fit standard 1-1/2 inch open-end drains, making it the ideal maintenance upgrade for yachts, center consoles, and kayaks.

Before ordering

  • Compare the listed dimensions with the installation area or existing part.
  • Select the correct size, model, voltage or configuration where options are offered.
  • Installation method and required hardware can vary by boat and mounting surface.
