What is a Deck Filler?

A deck filler is a fitting installed on the deck of a boat. It allows you to fill onboard tanks securely through a designated entry point. Deck fillers have a cap that can be screw-in, key-operated, or lockable to keep the opening safe and secure.

You need a deck filler to keep liquids safely stored on your boat. Without one, spills or leaks can happen, causing issues with your storage system. Deck fillers help keep your boat organized and protect the stored fluids from contamination.

Difference Between Nylon and Stainless Steel Deck Fillers?

Nylon deck fillers are lightweight and easy to handle. They’re great if you want an affordable option.

Stainless steel deck fillers are stronger and more durable. They’re resistant to saltwater and rough use, making them a better option for long-term use. Choose based on your needs and the type of boating environment you’re in.

Do All Deck Fillers Fit the Same?

No, deck fillers vary in size, shape, and fitting type depending on the manufacturer and purpose. Each one is designed to match a specific opening or tank fitting on your boat.

Choose a deck filler based on size, shape, and fitting type. Check the measurements to match your existing setup. Look at the fitting type to ensure it connects correctly.
