A set of two 38 mm deck fillers made of polished AISI 316 stainless steel – one labeled for Fuel and one for Water. These deck fill caps provide secure, leak-free access points for filling your boat’s fuel tank and water tank. Each filler has a screw-cap with an O-ring seal and comes with an integrated deck flange (fits into a standard 38 mm hose). The caps are clearly engraved (“FUEL” and “WATER”) to prevent cross-contamination. A chain tether keeps the cap attached to the deck fitting when open, so it won’t be lost overboard.

The 38 mm (1-1/2") neck size fits common hose sizes for fuel fill and water fill lines on most boats.
