Extreme Corrosion Resistance

To express our confidence, Attwood Stainless Steel Thru-Hull fittings are Guaranteed for Life!
Gasket for Caulk Free Sealing
For a durable, maintenance free sealing alternative, all our fittings come equipped with an optional silicone gasket. Customized specifically for each thru-hull flange design, our gaskets take the hassle out of assembly by eliminating the need for marine sealants and caulks.
