Buck Algonquin Bronze Through-Hull Fitting 1″

Buck Algonquin Bronze Through-Hull Fitting 1″

The 1″ through-hull is one of the most versatile sizes in marine plumbing large enough for solid flow on cockpit drains, bilge pump discharge, and raw water intakes, while still fitting neatly into standard hull penetrations. This Buck Algonquin fitting is cast from naval bronze for long-term corrosion resistance in salt, brackish, and fresh water environments.

Standard barrel length suits most production fibreglass hulls. Designed to pair with matching Buck Algonquin bronze ball valves and pipe/hose adapters for a complete, serviceable installation.

Parts Desk Insights

Best use case: The 1″ size is the most commonly requested through-hull for mid-size production boats it covers cockpit drains, bilge discharge, and smaller raw water intakes in one versatile fitting. Standard barrel length works for most fibreglass hulls; if a customer is working with a thicker hull (cored, wood, or older heavy fibreglass), check whether they need the long or extra-long version instead. Always confirm the customer is pairing this with a proper seacock or ball valve the matching 1″ bronze ball valve and pipe/hose adapter complete the assembly. Bronze is the correct material for below-waterline fittings; steer customers away from plastic alternatives for any through-hull that sits below the waterline.
