O-Rings are the most common seals. Due to their widespread use in a wide variety of applications, they are available in many different sizes, special shapes and materials. There are O-Rings in mechanical engineering, apparatus and container construction, special machine construction and fittings construction. O-Rings can also be found in the chemical industry, food industry, pharmaceuticals and sanitary industry. O-Rings also play an important role in maintenance. Whether in pneumatic, hydraulic or other applications. In today's world, O-Rings are small but omnipresent helpers with an important task.
That is why we at Westring Dichtungstechnik have taken the trouble to compile a comprehensive collection on the subject of O-Rrings. Here you will find basic information such as installation and application methods, as well as the mode of action. Of course, we also refer to the installation dimensions of O-Rings and different groove designs as well as surfaces. You will find the different guidelines for groove dimensions using different O-Rings, as well as standard and stock lists.
Not everything in sealing technology is self-explanatory. To help you, we offer you the O-Ring Handbook as a PDF free of charge. This helps you to understand various terms from sealing technology. You will find explanations of the Joule effect, expansion coefficients, sealing compatibility index (DVI) and other physical specifications. At the end of the O-Ring Handbook you will find notes on correct storage and information on the media resistance of elastomers. We also have a media resistance table available for you as a digital browser application (see below).
