It is molded entirely from fiberglass filled injection molded nylon, so it contains no metal and never requires grounding to the boat's electrical system, eliminating corrosion concerns common with metal deck fill caps.\u003c\/p\u003e\u003cp\u003eThe cap features a built-in key for easy removal and installation. The key can be locked in the upright position for quick opening and closing, or recessed into the cap for a flush surface when not in use. The cap measures 1-7\/8 inches in diameter with an 11-1\/2 NPSM straight thread pitch, matching Sea-Dog waste deck fill bodies. Black is the designated color for waste system deck fills, keeping tank fittings clearly identifiable and helping prevent misidentification and cross-contamination between waste, water, fuel, and gas fill points.\u003c\/p\u003e\u003cp\u003eThis is a cap-only replacement part; it does not include the deck fill body, mounting fasteners, or an attachment chain (chains are included with gas, diesel, and water replacement caps, but not with the waste cap). It is compatible with Sea-Dog hose deck fills and will not work with pressurized oil injection systems.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Sea-Dog\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 357094-1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Waste Deck Fill Replacement Cap\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCap Diameter:\u003c\/strong\u003e 1-7\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Pitch:\u003c\/strong\u003e 11-1\/2 NPSM straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Fiberglass filled injection molded nylon\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.09 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrounding Required:\u003c\/strong\u003e No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAttachment Chain Included:\u003c\/strong\u003e No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCap Removal:\u003c\/strong\u003e Built-in key, locks upright or recesses flush\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 035514357074\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eFits Sea-Dog waste hose deck fills using a 1-7\/8 inch diameter, 11-1\/2 NPSM straight thread cap opening.
