RUBBER SEALING O RING FOR A.537

157mm Waterproof External Hatch Cover – Marine Grade Deck Access

Keep your vessel watertight with this 157mm externally sealed hatch cover, engineered for reliable performance in demanding marine environments. Designed for kayaks, canoes, sailboats, and small craft, this hatch cover delivers a secure, weatherproof seal to protect your onboard storage from water ingress.
How It Works
The hatch body (gasket) is permanently mounted to the hull. An A.538 O-ring is seated around the gasket, beneath the retaining lip, creating a compression seal along the external diameter. The lid is then threaded and screwed down tightly, forming a watertight barrier around the outer edge of the hatch.

Available Options

3 colours to match your vessel's deck
With or without a hatch bag for versatile onboard storage solutions
