Vetus self-aligning inner bearing 25mm
The new Vetus ZWBH stern gland has been developed for use with water-lubricated stern gear.
The updated monoblock design works in the same way as the trusted ZWB seals, but with the addition of an extra lip seal, making three in total, for added security.
With minimal friction, oil and grease resistance and with a 10mm vulcanised rubber hose pillar for water injection the new ZWBH is ready for another round!
Vetus advises annual lubrication with silicon grease to keep the stern gear seal in optimal condition. ZWBH seals can withstand temperatures between -15° and + 85° and are suitable for Vetus bronze, steel or GRP stern tubes.
The set comes with two stainless steel hose clamps and grease.
Features:
- flexible, to absorb shocks and vibration
- triple lip seal keeps the water out
- 60-70 shore NBR rubber with brass hose pillar
- complete with water and grease injection points
- available for shaft diameters of 25mm, 30mm and 35mm (see our other listings)
