Key Performance Features

• Chrome-Plated Bronze: The cap is cast from high-strength bronze and finished with a mirror-chrome plating for maximum corrosion resistance in harsh saltwater environments.

• Interchangeable Inserts: Includes five distinct nameplate inserts, allowing you to customize the cap for your specific tank.

• Integrated Safety Chain: Comes with a pre-installed stainless steel "bead" chain to attach the cap to the fill body, preventing it from being dropped overboard during refueling.

• Gasket Included: Features a fuel-resistant O-ring/gasket to ensure a vapor-tight and watertight seal, preventing water intrusion into your fuel supply.

• Slotted Drive: The cap features a standard slot that can be opened with a traditional deck plate key or a large flat-head screwdriver.

Installation Pro-Tips

• Insert Seating: Before snapping your chosen insert into the cap, ensure the recess is clean and dry. Once the insert is pressed into place, it is designed to be permanent.

• O-Ring Maintenance: To prevent the cap from seizing and to ensure a perfect seal, apply a tiny amount of marine-grade silicone grease or PTFE lubricant to the O-ring once a season.

• Chain Attachment: When attaching the safety chain to the fill body, ensure the screw is tight. A loose chain is the #1 reason caps end up at the bottom of the marina.

• Don't Over-tighten: Hand-tight plus a quarter-turn with a key is usually sufficient. Over-tightening can compress the O-ring to the point of failure or make it nearly impossible to remove at the next fuel dock.
