O Ring 49″ Thick Earthmover PK 2 OR349T

The OR349T is a pack of two 49-inch thick O-rings designed specifically for earthmover tire assemblies. These O-rings are critical components for maintaining an airtight seal between the rim and bead seat ring in 3-piece and 5-piece wheel configurations, preventing air loss and ensuring tire integrity in demanding operational environments.

What You Get

• Two (2) O-rings, each 49 inches thick.
• Engineered for earthmover applications.
• Designed to create an air seal between the rim and bead seat ring.
• Suitable for 3-piece and 5-piece wheel assemblies.

Built For

These O-rings are built for heavy-duty earthmoving equipment, including but not limited to: large loaders, excavators, dump trucks, and other machinery utilizing multi-piece wheel assemblies. They are essential for tire technicians and maintenance crews performing tire changes, repairs, or routine servicing on such equipment where reliable air retention is paramount for operational safety and efficiency.

Construction

The O-rings are constructed from a robust, uniform black elastomeric compound. This material choice is standard for O-rings in high-stress applications, providing the necessary resilience, flexibility, and resistance to compression set required for maintaining an effective seal under the significant pressures and forces encountered in earthmover operations. The consistent black coloration indicates a standard rubber or synthetic rubber formulation optimized for durability and sealing performance.
