Application of NBR O-Rings and Buna O-Rings:Nitrile is the most widely used elastomer in the seal industry, and commonly used in o-ring and sealing applications. The popularity of nitrile is due to its excellent resistance to petroleum products and its ability to be compounded for service over a temperature range of -22°F to 212°F. Nitrile provides excellent compression set, tear, and abrasion resistance. The nitrile o-ring is commonly referred to as a Buna o-ring, or NBR o-rings. Datwyler offers a complete selection of both the standard AS568 o-ring and metric o-ring sizes.
