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.

Basic Material:
NBR
Commercial Description:
A 70 durometer, NBR elastomer. The properties of the nitrile rubber depend mainly on the ACN content which ranges between 18 % and 50 %. In general it has good mechanical properties with an operating temperature range of between -30 °C and +100 °C. NBR is mostly used with mineral based oils and greases and is a good choice for standard applications. Used also as an energizer in T46N, M12N, Z20N, and Z52N.
