The CW13-A scraper ring is specifically engineered to protect primary elastomer wipers from damage by scraping off hard and encrusted dirt in the harshest environments. This Dynamic component is designed to be used in tandem with CW01 or CW02 wipers on reciprocating rods. Featuring high stiffness stability and exceptional dry running properties, the CW13-A fits into H9 bore housings with small retaining shoulders. Utilizing advanced PTFE Hydraulic Seals and high-strength POM, this design ensures that sand, mud, and swarf are intercepted before reaching the internal sealing elements, significantly extending the service life of working cylinders.
