PSS PRO Shaft Seal 3" Shaft & 4-1/2" Tube

The PSS PRO Shaft Seal 3" Shaft & 4-1/2" Tube is a precision marine and industrial shaft sealing component designed to prevent water ingress and contamination in various applications. It is particularly suited for military and civilian watercraft, pumps, and propulsion systems, ensuring reliability in demanding environments.

This shaft seal features a progressive lip design and advanced elastomer compounds, which maintain consistent performance across extreme temperature and pressure ranges. The 3-inch shaft diameter and 4-1/2-inch tube configuration ensure a proper fit and load distribution, minimizing radial play and maximizing seal life. This design reduces the need for frequent maintenance, thereby lowering downtime and operational costs.

Operators of patrol boats, rigid hull inflatable craft, and various propulsion systems will benefit from the seal's proven track record in both saltwater and freshwater environments. The dual-action geometry provides effective sealing for both static and dynamic applications, protecting bearing assemblies and reducing wear from vibrations.
