Henleys Easiflow® stern tube system is a purpose-designed composite solution developed to replace traditional metallic stern tubes and rudder port housings, offering improved dimensional stability and long-term reliability. The major advantage is no corrosion of the bearing housing for the life of the vessel.

 

Manufactured to a precise internal diameter and formulated to prevent water absorption or swelling, Easiflow was designed to be used with our Thordon polymer bearings to ensure consistent alignment and low wear.

 

The system integrates seamlessly with most shaft-seal arrangements such as our Henleys Shaft Seal and can either be glassed directly into a fibreglass hull or epoxy resin chocked within a fabricated aluminium or steel outer tube, where the Easiflow tube is accurately aligned and permanently bonded to form a rigid, corrosion-free stern tube assembly.

​​

Henleys can supply standard sizes off the shelf in up to 5m lengths. We can also manufacture custom sizes either straight or with flanges fitted.
