Dripless Shaft Seals
The HENLEYS Shaft Seal™ represents our fifth generation of shaft seal design — the culmination of decades of marine engineering experience.
Engineered with Safety, Simplicity, and Longevity in mind, the HSS requires no grease or ongoing maintenance and is easy to install.
The HSS can be fully serviced while the vessel remains in the water, making it an ideal choice for commercial operators or anyone planning extended offshore operations.
Manufactured with premium-quality materials, the HSS can be fully refurbished as parts wear outside of acceptable tolerances.
An optional temperature sensor kit triggers both visual and audible alarms before damage can occur due to coolant loss, allowing safe inspection and return to port.
Available in imperial sizes from ¾” to 5” and metric sizes from 25mm to 130mm, with the option to manufacture custom diameters to suit unique applications.
