O-Ring
O-ring seals can be used as sealing elements,
and can also be used as force elements for hydraulic sliding seals and dust seals.
Therefore, it is widely used in various fields.
AS 568 A O-RING STANDARD SIZE
JIS B 2401 O-RING STANDARD SIZE
In the industrial field, whether it is a single seal for repair or maintenance,
or in applications that require quality assurance such as: aerospace, automotive industry and general industry, there is no O-ring seal that does not use it.
Used as a radial static seal, such as: the seal of shaft sleeves, seal covers, pipes, oil cylinders, etc.
Used as axial static seal, such as: flange, plate and end cover, etc.
In fact, there are a variety of rubber compounds available, some of which are listed below.
