Perko Garboard Drain & Drain Plug Assy Cast Bronze/Brass MADE IN THE USA

The Perko Garboard Drain & Drain Plug Assy Cast Bronze/Brass is a marine-grade through-hull fitting designed for boats, yachts, and watercraft requiring reliable bilge or cockpit drainage. This dual-material assembly combines a cast bronze flange with a brass plug to provide corrosion resistance in saltwater and freshwater environments. Garboard drains are essential for any vessel needing efficient water removal without compromising hull integrity or structural strength.

Constructed from premium cast bronze and brass—materials proven to resist galvanic corrosion in marine applications—this assembly features a 2-inch outside diameter flange with eight screw mounting points for secure installation. The 1/2-inch pipe size accommodates standard marine plumbing connections, while the brass drain plug allows controlled opening and closing of the water pathway. The bronze flange distributes fastening loads evenly across the hull, preventing stress concentrations that can lead to leaks or structural failure. Made in the USA, this component meets the durability standards expected by professional boat builders and experienced mariners.

Boat owners, naval contractors, and restoration specialists rely on Perko drain assemblies for below-waterline installations where failure is not an option. This garboard drain is ideal for replacing original equipment or upgrading older vessels with modern corrosion-resistant hardware. Installation requires proper hull sealing around the flange and secure fastening of all eight mounting points; compatibility with 1/2-inch through-hull plumbing makes integration straightforward on most recreational and commercial vessels. Weight of 0.3 lbs ensures minimal impact on vessel balance.
