Buck Algonquin Bronze Through-Hull Fitting — 3/4" Extra Long
A properly installed through-hull is one of the most critical fittings on any boat. This Buck Algonquin 3/4" extra-long bronze through-hull is built to last — cast from naval bronze for superior corrosion resistance in salt water, and sized with the extra-long barrel to accommodate thicker hull sections where a standard-length fitting won’t reach.
Buck Algonquin is a trusted name in marine plumbing hardware, and this fitting is designed to pair directly with matching bronze seacocks and ball valves for a complete, serviceable installation.

Parts Desk Insights
Best use case: The extra-long barrel makes this the right choice when a customer is working with a hull that’s too thick for a standard through-hull — common in older fibreglass boats, wood hulls, and cored construction. Always confirm hull thickness before ordering a standard vs. long vs. extra-long fitting. This is a safety-critical component: verify the customer is pairing it with a proper seacock or ball valve — a through-hull without a valve is not a compliant installation. The matching 3/4" bronze ball valve and pipe/hose adapter are the natural add-ons to complete the assembly. Buck Algonquin bronze is a premium, long-life choice over plastic or composite fittings.
