Perko Thru-Hull Fitting w/Pipe Thread Bronze MADE IN THE USA 2". Perko's engineered these Fixed End Fittings to ensure the strictest tolerances creating the highest performing watercraft possible. These Fixed End Fittings are cast from ductile iron meaning they can withstand the weight of heavy engines. However they are not cast from plastic meaning they are able to withstand the weight of your boat and propellers better than the competition. As a result theseThru-Hull Fittings are highly corrosion-resistant and you can mount them in even the narrowest of mounting holes. Plus the threaded end provides the torque necessary for installation. An added bonus; the threads are machined all the way around the flange ensuring you can torque them all the way down without stripping the threads. Every manufacturer has different fitting dimensions so make sure you select the right size for your boat and brand new experience.
