Selecting Oil Seals with the Right Pressure Ratings for Construction Equipment

Construction equipment hydraulics often operate under high pressure, and selecting oil seals with the correct pressure rating is critical for maintaining performance and avoiding failures.

Understanding Seal Pressure Ratings

• Dynamic vs. static pressure scenarios

• Impact of pressure surges and fluctuations

• Seal design features that influence pressure tolerance

Seal Selection Guidelines

• Refer to OEM pressure specifications

• Choose seals with built-in reinforcements for high-pressure zones

• Use pressure relief systems to extend seal life

Consequences of Underrated Seals

• Seal extrusion or blowout

• Fluid leaks under load

• Damage to mating components
