Introduction to Hollow O - ring
A hollow O - ring is a type of sealing element with a circular cross - section and a hollow interior. It is typically made from various elastomeric materials such as rubber, silicone, or fluorocarbon. The hollow design gives it unique properties compared to solid O - rings. It can provide a more flexible and compliant seal, making it suitable for applications where there are irregular surfaces, large tolerances, or where a lower sealing force is required. Hollow O - rings are widely used in industries like aerospace, automotive, medical, and food processing for sealing purposes, including preventing fluid or gas leakage.
