• High-Performance NBR90 Material: Made from premium nitrile rubber with Shore A 90 hardness, offering excellent oil resistance, wear resistance, and reliable sealing performance in demanding working conditions.

• Comprehensive Size Coverage: Includes 663 O-rings across 36 sizes, covering most common sealing needs for excavator maintenance and repair tasks.

• All-in-One Convenience: Eliminates the need to source individual O-rings separately, saving maintenance time and reducing procurement costs.

• Organized Storage: Comes in a sturdy, labeled plastic case with compartmentalized slots for easy size identification and quick access during repairs.

Working Principle

O-rings in the OR-KIT006 kit work on the classic compression sealing principle. When installed between two mating surfaces (e.g., hydraulic cylinder components, valve connections), the NBR90 O-ring is compressed and deforms to fill the tiny gaps between surfaces, creating a tight barrier that blocks fluid or gas leaks. The NBR material’s high elasticity allows it to adapt to minor surface irregularities, ensuring a reliable seal even under varying pressures and temperatures. With Shore A 90 hardness, these O-rings offer enhanced resistance to extrusion and deformation under high-pressure conditions, making them particularly suitable for heavy-duty hydraulic systems found in excavators.
