The Captain's Take
After years of battling leaky thru-hulls, I switched to Groco and haven't looked back. Their bronze fittings are top-notch. This 3/4" thru-hull with nut is no exception. It's easy to install, creates a rock-solid seal, and I know it's going to stand up to the test of time and the rigors of the sea. I recommend Groco to any captain serious about maintaining a reliable and seaworthy vessel.
