- Cast from certified Enhanced 316 Stainless Steel alloy for strength and lifetime corrosion-resistance
- All visible areas are polished to a mirror finish, then passivate each part for additional protection
- Thick steel sidewalls withstand continual stress and hose flexing
Faster, Simpler Installation:
- Each Thru-Hull is available with a new silicone gasket
- A channel under the flange holds a bead of sealant, making it easier to apply a trouble-free seal
