The Tides Marine RPB Type F unit is designed to be installed in rudder tubes which have been laminated or welded into a vessels hull.
The unit consists of a one-piece UHMW housing with a nitrile lip seal. It eliminates metal-to-metal contact and the associated problems of abrasion and electrolytic corrosion. It is 100% watertight and eliminates chatter and vibration, resulting in a quieter, smoother operation.
