O-Rings

O-rings are one of the most commonly used and most important components in machines utilised across a wide variety of different industries. O-rings are deceptively simple components – resembling no more than a circular ring of rubber material acting as a sealant between two machine parts. Behind their outward appearance, however, O-rings are the result of precision engineering and extensive development. There are thousands of different types of O-ring, each custom-designed to work with a specific machine type. We are one of the UK’s leading providers of industrial O-rings, and can accommodate bespoke orders to suit the machinery you use in your line of work.

How are O-rings used?

O-rings are used in virtually every engineering setting, especially in the hydraulics industry but also extending to all branches of industrial manufacturing. O-rings are also critical components wherever a water seal is required, for instance in showers, sinks and other plumbing applications. Different O-rings are required to accommodate different pressures, temperatures and liquid media.

How to order

Our team are here to help you with your business. Ordering O-rings from BSCL is a simple process. To get your order started we simply need the following information:

  1. The inside diameter = I.D
  2. The cross section = C.S.
  3. The compound (material) from which it is to be made 
  4. The hardness of the product if known

This is all the information we require to identify the precise O-ring you need. We use an 11 digit part number system as a means of precision identifying different O-ring varieties.
All O-rings are available in a range of colours. For information, please get in touch with our sales team by calling (01922) 646716.
