Scrapers

Scrapers are devices designed in sealing configurations, consisting of an Armorlene® PTFE Ring and either an Aerospace grade O-Ring or a metallic spring energizer.  Scrapers are installed into hydraulic cylinders,  designed to prevent dirt, foreign particles, Foreign Object Debris ( FOD ) or moisture from outer environment from entering the sealing systems as the rods retract into the system. This prevents contamination of the hydraulic system that could damage bearings, seals, and mating components.   Legacy single lip scrapers design keep contamination from the outside. Double-acting scrapers also remove the residual fluid film from the rod surface. Also, they minimize the ingression of small debris from entering the system and act as a secondary seal which avoids external leakage.  In addition, for systems with extreme working conditions, spring energized OptiSeal® scrapers can be specified. The OptiSeal® scraper performance is not restricted by an O-Ring element.
