The Captain's Take
After years of battling corroded and leaky thru-hulls, I switched to Groco and never looked back. Their bronze fittings are built to last, and the HTH series provides a consistently reliable seal. This 1 1/4" fitting is a workhorse – I use it for everything from engine cooling to washdown systems. Trust me, when you're miles offshore, the last thing you want to worry about is a failing thru-hull. Invest in Groco for worry-free boating.
