Introduction to Hollow O - rings
Hollow O - rings are a type of sealing element with a unique design. Unlike traditional solid O - rings, they have a hollow interior. This design provides several advantages. Firstly, they can offer greater compressibility, which means they can adapt better to irregular surfaces and variable clearances. This makes them highly suitable for applications where there are slight dimensional variations or where a more forgiving seal is required. Secondly, their lower hardness due to the hollow structure allows for a more uniform sealing force distribution, reducing the risk of over - compression and damage to the mating surfaces. Hollow O - rings are widely used in various industries such as aerospace, automotive, medical, and semiconductor manufacturing, where reliable sealing is of utmost importance.
