Sea-Dog Waste Deck Fill for 1-1/2 Inch Hose, 316 Stainless Steel, Part 351323-1

The Sea-Dog 351323-1 is a stainless steel waste deck fill designed for 1-1/2 inch hose, used to route sewage discharge or pump-out lines from the boat's waste holding tank to a deck-mounted fitting. It is constructed of corrosion resistant investment cast 316 stainless steel for long-term durability in a marine environment. The cap is slotted and requires a key to open and close, adding a layer of security against accidental or unauthorized access to the waste system. Unlike Sea-Dog's gas, diesel, and water deck fills, the waste version does not include an attachment chain for the cap. The deck fill installs with three #10 flat head fasteners (not included) and is sized for a 1-1/2 inch hose connection, with a cap diameter of 1-7/8 inches and an 11-1/2 NPSM straight thread pitch. As with other metal deck fills, USCG regulations require a bonding wire be connected to this fitting to prevent sparking. This is the complete deck fill unit; a matching replacement cap and separate stainless or nylon deck fill keys are also available if the original cap or key is lost or damaged, and a body-only fitting is offered separately for installations that only need the base without a keyed cap. Because the waste fitting is a specific part in the Sea-Dog deck fill lineup, be sure to select the waste-labeled version rather than the gas, diesel, or water variants, which use different cap markings and, in the case of gas/diesel/water, include an attachment chain.
