Attwood 66074-3 Replacement Deck Fill Cap and Chain, Fits Attwood 66126

The Attwood 66074-3 is a replacement cap and chain designed specifically to fit Attwood deck fill 66126. If the original cap on your 66126 deck fill has been lost, cracked, or worn out, this part restores a secure, watertight closure without requiring you to replace the entire deck fill assembly.

The cap is machined from enhanced 316 stainless steel alloy and finished with a high-polish surface for a clean, corrosion-resistant appearance on deck hardware. The flush cap is slotted so it can be opened and closed with a separate key (key sold separately), and it features an O-ring that seals the cap watertight when secured. The cap attaches to the deck fill body with an included stainless steel beaded chain, so it stays with the boat and cannot be misplaced during fueling or servicing.

This is a direct replacement part, not a full deck fill kit -- it includes only the cap and chain. It is intended for use on the Attwood 66126 deck fill.
