Attwood Marine 38761 Scupper Valve for Self-Draining Cockpits

The Attwood Marine 38761 Scupper Valve is designed to allow water to drain from self-bailing cockpits while preventing backflow from entering the boat. This essential marine drainage fitting features a one-way valve mechanism that opens under the pressure of water draining from the deck, then automatically closes to keep water out when the boat is at rest or when external water pressure increases.

Key Features:

• One-way valve design prevents water backflow into cockpit
• Self-draining operation for automatic water removal
• Durable marine-grade construction resists corrosion and UV damage
• Easy installation in scupper drain holes
• Reliable performance in saltwater and freshwater environments

Ideal for boats with self-bailing cockpits, this scupper valve helps keep your deck dry and safe by efficiently removing water while maintaining a watertight seal against incoming waves and spray. A critical safety component for any vessel with cockpit drainage systems.
