Sea-Dog Replacement Cap 351755-1 for 351750 and 351750-1 Gas Deck Fills, Keyless Chrome Plated Die Cast Zinc

The Sea-Dog 351755-1 is a replacement cap engineered specifically for the Sea-Dog 351750 and 351750-1 gas deck fills. It restores keyless operation to a worn or damaged deck fill without requiring replacement of the entire fitting. The cap uses easy-to-use tabs for keyless operation, so no deck plate key is needed to open or close it dockside or at the fuel pump.

Constructed of chrome plated die cast zinc, the cap measures 1-11/16 inches in diameter with a 12 SAE thread pitch to match the threading on the 351750 and 351750-1 deck fill bodies. An attachment chain is included, keeping the cap tethered to the deck fill body so it cannot be dropped or lost overboard during fueling. Installation is a simple thread-on replacement of the original cap, letting the rest of the deck fill assembly remain in place.
