Tethered Chain Stainless Steel Fuel Cap with Slotted Top

This stainless steel fuel cap is made from 316 stainless steel with a smooth silver metal finish, giving the marine hardware a clean, low-profile look for fuel and oil tank openings. Designed as a filler cap, it covers a marine fuel tank filler or oil filler port to help close the opening securely when not in use. The slotted top works with the matching small key, making it easy to turn and remove the fuel filler cap without relying on a large handle. A tethered chain keeps the cap connected to the fitting, helping prevent misplacement and keeping the oil filler cap close at hand during refueling. Built for marine use, this stainless steel fuel cap provides a practical cover for fuel and oil filler ports, supporting tidy, convenient access on board.
