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
All models have wrench flats or an end notch to hold as a gripping surface; one installer can tighten all connections from inside the hull
