Automatic breathable vent valves made from durable plastic. These valves deliver waterproof protection while allowing controlled airflow, preventing pressure-related stress on boards and keeping equipment in top condition. Easy to install on various board types, they are designed for everyday use by surfers who face changing sea conditions and climates. Key benefits Protects your board: Automatically regulates internal air pressure to prevent delamination, bulging, or other damage caused by pressure changes. Waterproof yet breathable: Keeps water out while allowing trapped air to escape or equalize, reducing the risk of moisture buildup and structural stress. Durable material: Constructed from robust plastic for long-term use in marine environments. Simple installation: Designed for easy fitting on a wide range of board types without complex tools. Reliable performance: Provides consistent pressure relief so your equipment remains functional and safe across different surf conditions. What it solves Eliminates pressure-related damage during temperature or altitude changes. Prevents internal moisture and pressure buildup that can degrade board integrity. Reduces maintenance needs by preserving the board’s structural condition. Compatibility and function Function: Automatic airflow regulation through a breathable venting mechanism that activates as pressure changes. Material: Durable plastic construction for corrosion resistance in saltwater environments. Compatibility: Suitable for installation on various board types that require venting to manage internal pressure. Practical use scenarios On long surf trips where water temperature and environmental conditions change, the valve keeps boards balanced and damage-free. During storage and transport, the valve prevents pressure buildup that can lead to delamination or deformation. For surfers who frequently change surfing locations or climates, the valve safeguards equipment against repeated pressure cycles. Protect your board with automatic, breathable vent valves that regulate air pressure, keep water out, and extend the life and performance of your gear.
