This straight thru hull fitting is molded from tough fiberglass reinforced resin and has a polished 304 stainless steel cap that is ultrasonically welded to the outer flange. The cap gives the upscale look of stainless and protects the flange from sun and salt (which is probably why you're replacing your old plastic thru hulls).
It has hose barbs to fit 1-1/8" ID marine hose.
Mounting nut is included. Designed for the value conscious customer, these fittings provide the look of a stainless steel thru-hull at a fraction of the cost
