Seacocks & Valves

Seacocks Thru-Hull Fittings and Marine Valves

Seacocks and thru-hull assemblies are among the most critical components of any boat, serving as the essential barrier between the interior of your vessel and the sea. A properly installed seacock valve is vital for safety, preventing catastrophic flooding in case of hose or appliance failure. Fawcett Boat Supplies stocks a complete line of high-quality marine seacock valve systems and thru hull fitting hardware, ensuring the integrity and safety of your boat's plumbing systems. When asking what is a seacock on a boat, know that it is the most dependable type of underwater valve available.

Safety and Thru-Hull Components

We provide comprehensive solutions for safely managing below-waterline openings, offering reliable alternatives to standard piping valves.

• Seacocks and Thru-Hulls: We stock true seacock units and their mating thru hull fitting parts. These are designed to be robust and permanently attached to the hull, creating a secure base for the plumbing. Every boat sea cock, and corresponding component meet high marine standards.
• Valve Types: Choose from conventional cone-type valves or modern, full-flow marine ball valve types. We provide seacock valves for boats in all sizes, including fittings suitable for popular dimensions like 3/4 livewell hose.
• Distinction: Many sailors ask, what is a thru hull fitting on a boat? It is the actual component passing through the hull, to which the sea valve (or thru hull valve) is attached. We offer both components for a complete, secure installation.

Quality and Compliance: Groco and Bronze

We prioritize quality, stocking components from industry leaders like Groco, specializing in durable materials like bronze.

• Groco: We are a trusted supplier of Groco seacock valves. The Groco bronze seacock valve is renowned for its superior construction and longevity, making it a preferred choice for serious boat owners due to its corrosion resistance and strength.
• Seacock vs. Ball Valve: Understanding the difference between a genuine seacock and a ball valve is crucial. A genuine seacock is mounted through-bolted to the hull and designed to withstand side loading forces, whereas a simple marine ball valve threaded onto a thru-hull fitting is weaker and less safe.
