Core Technical Specifications & Design Elements
• Material Construction: Professionally cast from precision-grade AISI 316 stainless steel, featuring a polished, mirror-like chrome top flange rim that ensures optimal corrosion, oxidation, and saltwater pitting resistance.
• Keyless Lifting Mechanism: Incorporates an ergonomic, fold-flat keyless lifting tab. This allows users to effortlessly lift the tab manually and use it as a structural handle to rotate and unlock the cap, completely removing the dependency on external deck plate keys.
• Hose Retention Ring Lines: The lower cylindrical barrel section features multiple molded concentric ribs designed to provide a high-friction mechanical grip for securing marine-grade intake hoses via heavy-duty hose clamps.
• Tank Security Tether: Comes equipped with an integrated stainless steel safety ball-retaining chain. This captive chain links the inner cap to the fill neck base assembly to prevent the cap from falling overboard or becoming misplaced during replenishment tasks.
• Leak Prevention: The inner threads of the removable cap feature a high-compression, oil- and water-resistant rubber O-ring gasket that creates a watertight seal.
Common Applications by Type
• FUEL / GAS: Intended for gasoline lines, typically paired with a built-in internal safety retention chain and an oil-resistant rubber O-ring seal to stop fumes and water intrusion.
• DIESEL: Used specifically for diesel lines to keep fuel ports safely color/text-coded across multi-tank deck configurations.
• WATER / WASTE: Utilized for fresh water tanks or waste holding tank suction fittings.
