Marinco 110R Sealing Collar and Threaded Ring for 30A Shore Power Inlets

The Marinco 110R is a sealing collar and threaded ring designed for 30A shore power connections aboard boats and marine vessels. This component threads onto the shore power inlet or connector to create a weathertight seal, helping keep moisture, salt spray, and debris out of the electrical connection point. Built from durable black plastic, the collar and ring assembly is sized to work with Marinco 30A shore power hardware.

This is a single-item replacement part, useful for boat owners who need to replace a worn, cracked, or missing sealing collar on their existing shore power setup rather than replacing the entire connector or inlet assembly. Keeping the sealing collar and threaded ring in good condition helps maintain a secure, corrosion-resistant connection at the dock.
