The Sea-Dog 351391 Angled Deck Fill Replacement Cap is an investment-cast 316 stainless steel cap designed to replace a lost or worn cap on a compatible angled hose deck fill fitting. The 1-1/2" to 12 NPSM straight thread provides a secure, water-tight closure at the fuel or water fill point.
Key Features
- Investment-cast 316 stainless steel — superior corrosion resistance for saltwater use
- Designed for angled hose deck fill fittings
- Thread: 1-1/2" to 12 NPSM straight
- Replacement cap only — fits compatible Sea-Dog angled deck fill bodies
- SKU: 354-3513911
Best Use Case
Use this cap to replace a missing or damaged cap on a compatible Sea-Dog angled deck fill fitting. The 316 stainless construction makes it the right choice for saltwater boats where lesser materials corrode quickly at the deck level. Confirm thread compatibility with your existing fill body before ordering.
