Description
Description

A Seal O-Ring is used to create a reliable and leak-proof seal between two mating surfaces. It is named after its circular or torus shape, resembling the letter "O." The O-ring works by being compressed between two mating surfaces, forming a seal that prevents the leakage of fluids or gases. It achieves this through its unique design, which allows it to deform and create a tight seal when subjected to compressive forces.

Attributes:
• Designed to provide a secure and reliable sealing
• Designed to resist wear, abrasion, and degradation caused by friction and exposure to various chemicals, oils, fuels, solvents, and environmental conditions

Applications:
A Seal O-ring is used to create and maintain the integrity of the seal and prevent fluid leakage in the Transmission Filter.

Warning:This product can expose you to chemicals including Lead and lead compounds, which is known to the State of California to cause cancer and birth defects or other reproductive harm. For more information go to www.P65Warnings.ca.gov.
