If you are looking for high-temperature FFKM O-Ring sizes suitable for your application, our downloadable size chart will allow you to select the exact size and tolerance for the correct AS-568A code.
FFKM O-Rings have a high temperature and chemical threshold, which means they are suitable for a wide range of industries and applications. Commonly used in the food, medical, oil and gas industries, these durable rubber O-Rings are incredibly versatile.
If you would like to understand how to measure FFKM rubber O-Rings, please take a look at our tolerance finder and size finder below. Simply enter a valid AS-568A code to find the FFKM O-Ring standard size most suitable for your application.
To use our size finder, enter the inside diameter of a valid rubber O-Ring seal and take a look at the available options. You can also select a cross-sectional thickness if you prefer. For example, for an inside diameter of 33mm, the options available to you include: the AS-568A code: 026, with a ring size of 31.47 x 1.78mm and a tolerance of 0.28/0.08 +- mm ID/Dia.
To find out more about how to measure up for your application, simply download our rubber FFKM O-Ring size chart, or contact the team at TRP Polymer Solutions.
