Forespar Marelon Full-Flow Seacock with Mushroom Through-Hull Seacocks

The Forespar Marelon Full-Flow Seacock with Mushroom Through-Hull is a complete, corrosion-free valve and through-hull fitting system for controlling water intake and discharge on boats. It is also called a marine seacock or thru-hull ball valve. It is made from Forespar's Marelon® polymer, so it won't corrode like metal fittings can.

Key Features:

• Integrated 2-part system: The Marelon® valve comes paired with a properly matched mushroom-head through-hull.
• No thread mismatches: The valve and through-hull are designed together, which avoids thread style mismatches between the two parts.
• Strong buttress-type threading: The mushroom-head through-hull uses a buttress-style thread.
• Full-flow design: The valve has an integrated hose connector.
• Meets industry standards: It exceeds ABYC H-27 standards and is UL approved.
• Versatile mounting: It is approved for use above or below the waterline.
• Corrosion-proof construction: The exclusive polymer formulation never corrodes.
• Emergency preparedness: A handle cap through-hull plug is included.

This seacock suits sailboats, powerboats and other vessels. Typical uses are raw water intakes, cockpit drains, livewells and other plumbing. Choose the child item that matches your hose and hull cut-out requirements.
