They are manufactured in standard or inch sizes, and metric sizes and can be made from almost any elastomer. The most commonly used is Buna (also called nitrile). Buna is used often because of its good mechanical properties, its resistance to lubricants and greases, and its relatively low cost. Other elastomers are also used based on their resistance to certain chemicals or various high or low-temperature ranges, add a myriad of design and application factors.
