English
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.

M12
Colour:
Dark Grey
Basic Material:
PTFE
Filler:
Virgin PTFE compounded with Turcon®, mineral fibre and additives
Commercial Description:
Turcon® M12 is a modern compound and the new standard industrial material. A development of thorough benchmarking and performance testing, Turcon® M12 offers low friction, high wear resistance and costs on par with standard bronze-filled compounds. This material is designed to be the first choice for seals used with linear motion, replacing standard (medium-filled) industrial bronze-filled compounds. Used in article numbers ending in M12N and M12V.
N7
Colour:
Black
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.
