O Ring 33″ Thick Earthmover PK 2 OR333T

The OR333T is a purpose-built sealing component for heavy-duty earthmoving equipment. This O-ring is engineered to establish and maintain a critical air seal within multi-piece wheel assemblies, directly preventing air loss and ensuring tire integrity under demanding operational conditions.

What You Get

• One (1) O Ring 33″ Thick Earthmover
• Pack of two (2) units
• Designed for precise fitment in the groove between the rim and bead seat ring on 3-piece and 5-piece earthmover wheel assemblies.

Built For

This O-ring is specifically designed for professional tradespeople working with large-scale earthmoving machinery, including but not limited to wheel loaders, excavators, dump trucks, and other heavy construction or mining vehicles utilizing multi-piece rims. Its primary function is to secure the pneumatic seal of tires, crucial for operational safety and efficiency in rugged environments.

Construction

The OR333T is constructed from a robust, high-density elastomeric material, characterized by its uniform black coloration. This material is selected for its inherent resistance to compression set, abrasion, and environmental degradation, including exposure to UV, ozone, and various chemicals commonly encountered in heavy equipment operations. The consistent thickness and smooth finish indicate a manufacturing process focused on dimensional stability and sealing effectiveness, critical for preventing air leakage in high-pressure tire systems.
