Non-Standard 90A Nitrile O-Rings are made from a harder durometer Buna-N (nitrile) than standard 70A AS568 O-rings and are designed for applications requiring inch sizes not specified by the SAE AS568 standard. Selected for higher-pressure and more demanding sealing applications than 70A nitrile, these O-rings range in inside diameter from 1-3/8" to 4-3/8", all with a four-series cross-section (.25"). Not recommended for use with brake fluid. Bulk discounts are available for large quantity purchases.
