Introduction to Hollow O - ring
A hollow O - ring is a type of sealing element. It is designed in a circular cross - section with a hollow interior. This unique structure gives it several advantages over traditional solid O - rings. The flexibility provided by the hollow design allows the O - ring to better adapt to irregular surfaces and uneven pressures. It can be compressed more easily, creating a more effective seal in applications where there are variations in the mating surfaces. Hollow O - rings are widely used in industries such as automotive, aerospace, fluid handling, and medical devices, where reliable sealing is crucial to prevent leakage of gases or liquids.
