Boarding and Venting

Fuel filler caps allow for quick and safe refueling without having to access the tank directly, while vents maintain proper ventilation, preventing overpressure or air pockets during filling and cruising. Available with a 38 mm or 50 mm rear hose connection, these components are made of mirror-polished 316 stainless steel, anodized aluminum, and UV-resistant technopolymer to match the style and budget of any vessel. Fuel, water, and waste versions are color-coded or laser-engraved to prevent incorrect refueling and can include a safety chain, hydrocarbon-resistant NBR gaskets, and keyed locking systems to protect the tank's contents. Vents offer anti-splash grilles and optional anti-siphon valves, compliant with ISO/ABYC standards, ensuring continuous air circulation and preventing the ingress of bilge or rainwater. Select the diameter, material, and function to find the cap or vent best suited to your fuel system.
