Stainless Thru-Hull Connectors

Polish your image with the new Standard Thread Thru-Hull. Why specify plastic parts when these fittings will last the life of the boat?

Rugged Stainless Construction

Cast from certified #316 Stainless Steel alloy for strength and lifetime corrosion resistance.
We polish all visible areas to a mirror finish, then send each part through passivation for additional protection.
Thick steel sidewalls withstand continual stress and hose flexing.

Faster, Simpler Installation

A channel under the flange holds a bead of sealant, making it easier to apply a trouble-free seal.
All sizes have wrench flats to hold as a gripping surface. One installer can tighten all connections from inside the hull.
Barbed tail ends provide plenty of room to hold multiple clamps.
