50mm Boat deck fill fillers with an angled neck, flip cap, and keyless/flip-tab design provide a durable, corrosion-resistant solution for marine fuel, water, or waste tanks.
Key Features & Specifications
• Material: Marine-grade 316 stainless steel, offering high resistance to saltwater corrosion and oxidation.
• Size Options: Available commonly in 1-1/2" (38mm) or 2" (51mm) diameter hose sizes to match standard marine plumbing.
• Design Type:
• Angled Neck: Makes filling easier in tight or sloped deck spaces.
• Keyless Flip Cap: Features a built-in lifting tab so you can twist and open the cap without needing a separate deck key.
• Chain Attachment: Many models include a stainless steel chain connecting the lid to the body to prevent loss.
Sealing: Equipped with rubber O-rings and gaskets to ensure a tight, leak-free seal against water or fuel intrusion.
Common Applications

Caravans, campervans, and motorhomes.

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.
