Buck Algonquin Bronze Pipe/Hose Adapter 3/4″ Pipe x 1″ Hose

This bronze adapter bridges the gap between a 3/4″ pipe-threaded seacock or ball valve and a 1″ hose a common size transition in marine plumbing systems where the valve thread and hose diameter dont match directly. Cast from naval bronze for long-term corrosion resistance in salt, brackish, and fresh water.

A clean, reliable way to complete a through-hull assembly without improvised fittings or reducers. Designed to work with Buck Algonquin bronze through-hulls and ball valves for a fully matched, serviceable installation.

Parts Desk Insights

Best use case: This adapter is the right pick when a customers valve thread and hose size dont match specifically a 3/4″ NPT valve outlet stepping up to a 1″ hose. This is a common scenario in cockpit drain and bilge discharge plumbing where the seacock is 3/4″ but the hose run is 1″. Always confirm both the pipe thread size on the valve and the hose ID before recommending an adapter. Bronze is the correct material for any fitting in a below-waterline or raw water system avoid plastic or brass in these applications. If the customer needs a same-size connection, point them to the 3/4″ adapter or 1″ adapter instead.
