Engineered for Maximum 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, ensuring 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.
Frequently Asked Questions
- Will this scupper valve prevent water from entering my boat when at a standstill?
- Yes. The valve utilizes a neutral buoyancy polyethylene ball that floats into a sealed position when external water pressure (from waves or resting depth) is applied, effectively blocking backflow while remaining ready to open when deck water needs to drain.
- Is the polycarbonate housing durable enough for rough saltwater conditions?
- Absolutely. We use high-impact, UV-stabilized polycarbonate engineered specifically for marine environments. It resists yellowing, cracking, and impact better than standard ABS plastics commonly found in lower-end scuppers.
- Does this require special tools for installation on a 1.5-inch drain?
- No. It is designed as a seamless retrofit for standard 1-1/2 inch open-end drains. The universal hole pattern allows for quick mounting with basic hand tools using the provided corrosion-resistant hardware.
