Perko - Thru-Hulls for Hose These Thru-Hull connectors by Perko are available constructed of cast bronze or chrome. The connection flange is machined to fit the hull and is grooved to retain bedding compound. Includes the nut. Thru-Hull fittings for hose are not recommended for below the waterline use.
The fittings seem more robust than as described, which is good. And more robust than the originals which are only 27 years old. We'll see if these ones hole up as well in sea water.
