The Trelleborg Turcon® Excluder® 2 is a double-acting O-Ring energized scraper that has two functions:

a) to scrape contaminants from the retracting piston rod to prevent soiling of the system and

b) to hold back the residual oil film on the extending piston rod on the medium side. The O-Ring maintains the pressure while the Excluder® 2 performs the scraper function. Excellent sliding properties and stick-slip free.
