Cadmium plated with gold chromate to QQL-614 and are inspected for required radial pressure, breakout friction, and rod light-tightness per spec. Manufactured to the MS28776 specification in accordance with the MIL-S-5049 procurement standard.

AM scrapers are typically used in heavy duty hydraulics like aircraft landing gear and steel mill cylinders.

Seal Options

• Solid scraping body only
• Scraping body with a narrow groove accommodating a serpentine form spring to scraping load
• Scraping body with a wide groove in the outside diameter accommodating two “c” style springs (resembling split washers) to generate scraping load
