No leaks, no drips, no worries; the new ZWBH sealson: Nov 20, 2018
VETUS continues to develop its renowned stern gland systems: please meet the ZWBH! ZWBH seals are developed for use with water lubricated stern gear. This updated monoblock design works in the same way as the trusted ZWB seals, with the addition of one extra lip seal (three total) for added security. Minimal friction, oil and grease resistant and with a 10 mm vulcanised hose pillar for water injection; the ZWBH is ready for another round!
Self-aligning inner bearing and triple shaft seal for extra security
VETUS advices annual lubrication with silicon grease to keep this 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. The ZWBH25 is available from stock, the other two versions will be available from February 2019.
