There are many benefits to using o rings. They: – can be used in static and dynamic applications – utilize very little space – efficiently seal pressure from both directions – are available in a range of materials to suit almost any application.
We stock a large range of metric, imperial, standard and non standard sizes. If required, we can also have o rings custom made to customer requirements, whether it be for a one off or large volume quantities.
