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.

Parts Desk Insights

Best use case: The extra-long barrel makes this the right choice when a customer is working with a hull thats 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.
