O-rings are widely used static sealing elements and are produced in a wide range of sizes, from commercial o-rings to high perfoamnce o-rings.

​

As SEM Industrial, we work on high perfomance o-rings used in critical applications which requires higher enginering inputs, rather than commodity o-rings. Examples of these applications include challenging conditions such as RGD, methanol, H2S, acidic or basic fluids, and very low temperatures.

​

James Walker manufactures o-rings in accordance with global standards such as ISO 3601, DTD, SAE AS 568, AS9100. We support maintenance and design engineers in the selection and supply of optimum o-rings for equipment/process.
