Buck Algonquin Bronze Ball Valve — 3/4"
A reliable, full-bore bronze ball valve for marine seacock and plumbing applications. This 3/4" valve is designed to be installed directly below a through-hull fitting, giving you a positive shutoff for any raw water intake, cockpit drain, bilge discharge, or exhaust outlet. One quarter-turn opens or closes the valve completely — fast and dependable when it matters.
Cast from naval bronze for long-term corrosion resistance in salt, brackish, and fresh water. A direct-fit companion to Buck Algonquin bronze through-hulls and pipe/hose adapters for a fully matched, serviceable installation.

Parts Desk Insights
Best use case: The 3/4" ball valve is the most commonly requested seacock size for smaller through-hull assemblies — cockpit drains, bilge discharge, and smaller raw water intakes on production boats up to about 35 ft. It’s the correct valve to pair with the 3/4" extra-long through-hull and either the straight adapter or 90° elbow adapter depending on hose routing. Remind customers that seacocks should be exercised (opened and closed) at least once a season to prevent seizing — a seized seacock is a safety hazard. Bronze is the correct material for below-waterline valves; steer customers away from plastic or brass alternatives in these applications.
