Perko Gas Cap with O-Ring and Retainer, Fig. 1270 Deck Fill Replacement Cap 1270DPG99A

The Perko 1270DPG99A is a Fig. 1270 gas deck fill replacement cap, sold complete with its O-ring and retainer. It is designed to replace a worn, cracked, or missing cap on a Perko Fig. 1270 gas deck plate, restoring a tight seal at the deck fitting where fuel is loaded into the boat's tank. The cap is made of zinc alloy with a zinc finish and a black color, giving it corrosion resistance for exposure to salt air, spray, and deck traffic. It uses a twist-on closure, so it threads and seats onto the deck plate body without tools for everyday use, while the included O-ring provides the seal against water intrusion and the retainer keeps the cap captive to the fitting.

This cap is intended for the gas (fuel) version of the Fig. 1270 deck plate line; Perko also offers matching Diesel and Water caps with O-ring and retainer for the same deck plate body, so boat owners should confirm they are ordering the gas-marked cap for a fuel fill. Replacement O-rings for this cap are also available separately from Perko, and a deck plate key is offered for opening and closing Fig. 1270/1269 deck plate caps. This is a functional replacement part for maintaining a watertight fuel deck fill, not a full deck plate assembly.

How does the cap attach to the deck plate? It uses a twist-on closure that threads onto the Fig. 1270 deck plate body and is held captive by the included retainer.

Are replacement O-rings available separately for this cap? Yes, Perko sells O-rings for the Fig. 1270 and 1269 cap line separately, packaged two per bag, for owners who only need to replace a worn seal rather than the whole cap.
