Wipers

MRW, 56mm Brass Cad Plated Rod Wiper

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

AN wipers are ideal for light duty and pneumatic applications. Its main purpose is to prevent dirt and contaminants from entering the hydraulic or pneumatic systems.

AN wipers will retrofit into glands prescribed in MS-33675 for corresponding dash numbers of MS-28776.

• Flexible, snap-in design for easy installation into closed housings
• Low compression set

Wipers are installed in hydraulic cylinders to prevent dirt, dust, and moisture from entering the cylinder as they retract back into the system. A hydraulic wiper prevents contamination that could damage wear rings, seals, and other cylinder components.
