For linear and reciprocating dynamic seal applications

The function of a wiper, scraper or excluder is to wipe or scrape dirt from the rod or shaft to prevent dirt particles from entering the hydraulic or fluid circuit of cylinders valves, thus dramatically increasing the service life of the seal and the equipment. Particular attention should be drawn to the selection of the wiper. For maximum seal life, it is important to protect the scraping edge of the wiper from being damaged.

 

We offer these types of wipers:

• Snap-in wipers, scrapers, excluders
• Press-in wipers
