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. The barbed tail ends provide plenty of room to hold multiple clamps. Stainless Steel Straight Thru-Hulls, Barbed. Standard Thread model has a full-length thread for thick hulls and easy tightening.
