The CW27-F is a high-performance double-acting PTFE wiper specifically engineered for heavy-duty industrial applications such as construction machinery, large-scale presses, and hydraulic actuators. This Dynamic scraper ring operates effectively on reciprocating and swivelling rods at pressures up to 16 Bar (232 PSI), featuring a patented back-to-back lip design energized by a flexible O-ring. As a robust alternative to Turcon® Excluder® 5, it offers outstanding sliding properties and stick-slip-free operation, effectively compensating for rod deflections. Utilizing advanced high-performance polymers, the CW27-F ensures a superior sealing effect against residual oil films while reliably scraping off firmly adhered dirt and environmental contaminants in extreme working conditions.
