Leaking deck fills, missing caps, and corroded fittings are among the most common — and most preventable — problems on any boat. This 316 stainless steel marine deck fill solves all three. A stainless steel bead chain keeps the key-lock cap permanently attached so it can never be lost overboard, while the flip-cap versions offer tool-free one-hand access. Built from marine-grade 316 SS with a polished finish, it resists saltwater corrosion, UV degradation, and heavy use season after season. Available in Gas, Fuel, Diesel, and Waste versions — clearly labeled to prevent cross-contamination and misfueling.
