O-Rings and O-Ring Cord


Here at Ashley Power we stock a wide selection of o-rings in a variety of materials including Nitrile, Viton, Silicone and EPDM.

O-rings are designed to be seated in a groove and compressed by two or more parts during assembly to form a seal. They are one of the most common seals found in machine designs because they are competitively priced, easy to make, reliable and have the simplest mounting requirements. We stock o-rings in various metric and imperial standard sizes. These sizes are specified by the inside diameter and the cross section (thickness).

Ashley Power can supply non standard sizes of o-rings which are available on request. Special sizes can be moulded and for smaller quantities they can be either butt or scarf jointed.

O-rings are used in a wide range of applications such as marine, agricultural, food production, automotive, etc and by using the different materials available it is possible to seal against many different types of media and temperatures.

In addition to metric and imperial o-rings we can also offer a variety of o-ring cord in a wide range of materials along with the adhesive to make your own. Our o-ring cord is available in sizes ranging in thickness from 1mm upwards. We can also supply metric and imperial o-ring selection boxes and o-ring splicing kits containing a variety of different sized lengths of o-ring cord and the tools needed to create your own custom sizes. for more infomation about our o-ring selection kits and oring splicing kit see our special offers page.
