Launching Zurcon® Scraper DA24 Venting Version



Trelleborg Sealing Solutions launches the Zurcon® Scraper DA24 Venting Version double-acting scraper. This is especially for severe operating conditions in fluid power applications such as hydraulic systems in off road vehicles. Its unique venting design incorporates pressure relief valves to prevent system failure.

Off road vehicles are a typical application for the Zurcon® Scraper DA24 Venting Version

Zurcon® Scraper DA24 Venting Version is based on the well established double-acting scraper DA24 which has proved effective in applications within aggressive environments for many years, especially where there is a high level of external contamination and dirt.

However, in some situations when there is pressure build-up behind the scraper, the scraper can be pushed out of the groove causing total sealing system failure. Zurcon® Scraper DA24 Venting Version has axial holes through the section which operate as pressure relief valves, allowing oil to be released in the case of overpressure. With improved stability in the groove the Zurcon® Scraper DA24 Venting Version becomes one of the most efficient scrapers available on the market.

Benefits of Zurcon® Scraper DA24 Venting Version

o Excellent scraping performance
o Superior protection against ingress of dirt, external media and moisture
o Efficient sealing behavior
o Advanced friction characteristics
o Limited heat generation, extending service life
o Stability in the groove securing function

DA24 Venting Version is produced in Zurcon®, the Trelleborg Sealing Solutions proprietary thermoplastic polyurethane material specially developed for sealing applications. This provides long service life under harsh working conditions and resistance against installation damage.
