1-2 weeks delivery time The Tides Marine SureSeal Lip Seals are replacement shaft lip seals offered in imperial (3/4″ to 5″) and metric (25 mm to 125 mm) sizes. Each variant is defined by its shaft diameter, part number, and exact seal dimensions including Lip Seal ID, OD, and thickness (in inches or millimeters depending on series). This range is intended for matching the correct seal to a specific propeller shaft diameter and housing size in marine driveline applications.

1-2 weeks delivery time The Tides Marine Spare Seal Carrier Kits are designed to store spare lip seals directly on the propeller shaft between the SureSeal® housing and the shaft coupling, allowing quick replacement of worn seals without uncoupling the shaft and, if required, without hauling the vessel out of the water. The carrier is a lightweight two-piece composite housing that clamps around the shaft and holds spare lip seals. Available in imperial sizes from 7/8″ to 6″ and metric sizes from 25 mm to 130 mm, the kits store one or two spare seals depending on shaft diameter.

What types of Tides Marine seals are used in propeller shaft installations?
Tides Marine offers shaft sealing products and related components for inboard propulsion systems, including complete shaft seal assemblies, replacement seals, spare parts, and service components for different shaft diameters and installation layouts. These products are designed to maintain a reliable seal around the rotating propeller shaft while supporting straightforward installation and servicing.
Systems such as the Tides Marine SureSeal use a self-aligning design to help maintain consistent sealing performance while accommodating normal shaft movement and minor installation variation.
What are the key features of the Tides Marine SureSeal shaft seal?
The Tides Marine SureSeal is a drip-free propeller shaft seal designed for inboard marine applications. It uses a self-aligning housing, flexible hose connection, internal bearing surface, and replaceable sealing components to maintain reliable contact around the shaft during operation.
Its design helps reduce side loading on the seal and allows the assembly to follow small amounts of shaft movement, supporting consistent sealing and long service life when correctly installed and maintained.
How do replacement seals and service parts help maintain Tides Marine shaft seal systems?
Replacement seals and service components allow worn parts to be renewed without replacing the complete shaft seal assembly. Using the correct parts for the shaft size and seal model helps restore proper sealing performance and extend the service life of the installation.
Regular inspection of the seal, hose connections, clamps, and related components is also important for identifying wear early and maintaining reliable operation of the Tides Marine shaft sealing system.
