This seal is integral to maintaining the integrity of fluid systems, ensuring that fluids remain contained and do not leak, which is vital for the efficient operation of the truck.

Basic Concepts of O-Ring Seals

An O-Ring Seal is a type of gasket with a circular cross-section, designed to create a seal between two or more parts. In mechanical systems, O-Ring Seals are used to prevent the leakage of fluids and gases. They operate by being compressed between two surfaces, which creates a tight seal that can withstand pressure and environmental conditions. O-Ring Seals are commonly made from elastomers, which provide flexibility and resilience ¹.
