Extreme Corrosion Resistance
As with all Attwood’s stainless steel products, these new fittings are cast from our proprietary stainless steel alloy. An enhanced version of 316 stainless, our stainless steel has proven to provide even greater corrosion resistance than competition’s standard #316 stainless. 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.

Caution: Thru-Hull connectors are designed for installation above the water line only.
