AVALON® SCRAPERS/WIPERS

Versatile scraper design
There are several Avalon® scrapers available to meet each application’s unique challenge:

  • 4186 Scraper: A rubber-spring energized scraper with an endless PTFE jacket (ring). The elastomeric energizer is situated on the centerline, reducing the tendency to roll out if the primary seal leaks. These designs can be a direct replacement for M28776 scrapers.
  • 2280 Scraper: A bidirectional wiper utilizing an O-ring energizer. These designs fit the same grooves as the BACS34A (Boeing) scraper.
  • 2145 Scraper: A metal garter-spring energized scraper with a scarf-cut PTFE ring. These designs can be a direct replacement for M28776 scrapers.

FEATURES & BENEFITS

  • Excellent wear resistance resulting in extended service life
  • Maximum exclusion capabilities for elimination of contamination ingression
  • Virtually eliminates scrapers’ rolling and twisting, resulting in extended service life
  • Offered in a variety of configurations to meet most of the standard glands used in today’s existing aircraft applications
