Nitrile Lip Seal, 2.000" Shaft Dia (StrongSeal)

Tides Marine replacement nitrile lip seals are specifically designed for each sealing system (propeller shafts / rudder stocks) produced by Tides Marine.
They are the only lip seals covered under the Tides Marine Warranty.
The outer shell is made of an Aramid fiber composite which is integrally molded to a rubber hinge with a nitrile edge. A 316-stainless steel garter spring is incorporated to distribute loads evenly over the propeller shaft or rudder stock.

SureSeal vs StrongSeal
The SureSeal drip-free propeller shaft seal is the model currently offered by Tides Marine. It replaced the StrongSeal in the year 2000.
The StrongSeal has a stainless steel band around the front of the housing to maintain the Lip Seal dimensions. The Lip Seal is held in place by a Retaining Ring.
The current SureSeal model has 5 or 6 Phillips-head screws (depending on propeller shaft size) in the face with a removable Cap and Split Washer. Some of the caps and collars are Pentagonal and some are Round. There is no difference between the Pentagonal and Round Caps other than their shape and number of fasteners. The Lip Seal has a recess all around it to make removal of the Lip Seal easy using only a small flat-bladed screwdriver.

NOTE – When ordering a spare seal carrier, for an existing Tides shaft seal installation, you must first determine if you have a SureSeal® or a StrongSeal® (last produced in 2000). This is because the lip seals for some shaft sizes are NOT interchangeable between these models of shaft seals.
If you are unsure, use the accomanying diagram to help identify the type of Tides shaft seal you have.
