Sea-Dog Locking Water Deck Fill, 1-1/2 Inch Hose, 316 Stainless Steel

This Sea-Dog deck fill is marked for Water and is built to accept a 1-1/2 inch hose, making it the fitting to install where a boat's fresh water fill line meets the deck. It uses a locking cap to help prevent tampering: the cap spins freely while in the locked position, and to unlock it the key is turned until the keyhole lines up with the cap tabs. Two keys are included along with a cap attachment cable so the cap cannot be misplaced once removed.

The cap has a 2-1/8 inch diameter with an 11-1/2 NPSM straight thread pitch, and the deck fill is color-coded with an international symbol so crew and fuel dock staff can identify the Water fill at a glance. The body is constructed of investment cast 316 stainless steel for corrosion resistance and long-term durability in a marine environment. It installs with three #10 flat head fasteners (not included). As with other through-deck fittings that connect to below-deck lines, USCG regulations require a bonding wire be attached to prevent sparking.
