O-rings are perhaps the simplest and most universal seal designs ever developed and are a fundamental element of machine design. O-rings are available in various metric and inch standard sizes. Sizes are specified by the inside diameter the cross section diameter (thickness). In the US the most common standard inch sizes are per SAE AS568B specification (i.e. AS568-214). ISO 3601-1:2008 contains the most commonly used standard sizes, both inch and metric, worldwide. The UK also has standards sizes known as BS sizes, typically ranging from BS001 to BS932. Other size specifications also exist.
O-rings are used as static, dynamic, radical or face seals- all with a wide range of rubbers. All of our o-rings are made according to international standard: ISO 3601, AS 568A, DIN 3771, JIS B2401. We meet the highest industrial standards and requirements of our customers.
