GROCO 3/4" Bronze High Speed Thru-Hull Fitting w/Nut

The GROCO 3/4" Bronze High Speed Thru-Hull Fitting with Nut is an essential component for serious boaters seeking reliability in both saltwater and freshwater applications. This fitting serves as a sealed penetration point for seawater cooling systems, livewell intakes, and transom drains, where leaks can jeopardize the integrity of your vessel.

Constructed from high-quality bronze, this thru-hull fitting offers superior corrosion resistance, particularly important for boats operating in saltwater environments. Its high-speed design minimizes turbulence and pressure drop, ensuring efficient flow through cooling systems and intake lines while preventing cavitation damage. The 3/4" diameter is suitable for mid-size recreational and commercial vessels, and the included nut allows for flush mounting through hull materials of varying thickness.

Anglers and charter operators who spend long hours on the water will appreciate GROCO's reputation for zero-failure performance under the stress of continuous engine cooling cycles and variable sea states. This fitting is designed to withstand multiple hull refinishes and engine rebuilds when properly installed and maintained with zinc anodes, making it a reliable choice for any boating enthusiast.
