Dynamic Seals Scraper A3

The Scraper A3 consists of a PTFE element with two wiper edges and an O-ring as preload element. The Scraper A3 has excellent sliding properties, runs stick-slip free and has good media resistance. This is ideal for all applications with heavy dirt infestations. The second sealing lip wipes off the residual oil film from the rod.

This is ideal for large installation spaces in comparison to the A2 design, especially suitable for heavy use. The PTFE compound is filled with bronze or carbon graphite to improve the compressive strength. O-rings are available in a variety of different materials.
