Description
RPB-I-2750 – Tides Marine Rudder Port Seal Type I (aye) for a 2 3/4 inch rudder stock.
Tides Marine TYPE-I Rudder Seals are retrofit units which are used with existing bronze port bearings. Consisting of a one-piece UHMW plastic housing with nitrile lip seal, they were developed to replace the flax-packing and sealing nut assembly. They are connected to the bearing by a flexible hose which keeps the nitrile lip seal in alignment with the rudder stock.
The TYPE-I will minimally increase the overall height of the port assembly but is 100% watertight and maintenance free. Performance improvements include quieter, easier and smoother steering.
Included with each unit is a protective cone to prevent damage to the lip seal during installation. A pre-cut length of the soft wall hose (purchased separately) must be used with each TYPE-I Rudder Seal for warranty coverage to apply.
Note: This product is a seal only. It provides no bearing support for the rudder. It is generally more economical to eliminate the dual cost of a rudder port and this seal by using one of our other sealed bearing systems, such as a Type D, Type C or TS.

Tides Marine Type I Rudder Seals are retrofit units which are designed to replace hose-mounted rudder stuffing boxes. They are connected to the existing bronze rudder port with a flexible hose which aligns the unit with the rudder stock.
The assembly consists of a one-piece UHMW housing and a nitrile lip seal. The Type I will slightly increase the overall height of the rudder port assembly.
These 100% watertight units provide quieter, smoother operation. A pre-cut length of soft-wall hose (purchased separately) must be used with each Type I Rudder Seal for warranty coverage to apply.
To determine which part to order, measure the exact diameter of the rudder stock (.000″) and the O.D. of the bronze rudder port to which the unit will be connected. Note your combination of rudder stock diameter and rudder port O.D. in the table on the Imperial or Metric size page. Confirm that there is sufficient space to accommodate the flange height and the barrel height plus 1″ of space between the Type I unit and the rudder port. Finally, confirm that there is clearance for the O.D. of the Type I assembly.

The following is a description of the installation procedures associated with the RPB Type-I rudder seal. Installation instructions are included with each unit and should be followed closely.
Note: Before installing the rudder, insert the red installation hat into the lip seal. When rudder is in place, remove, invert and replace it on top of the Type-I unit to keep debris off the lip seal during use.
