Storage
Do O-Rings Expire? Here's the Straight Answer
Most O-Rings outlast the drawer they sit in. Here's how long each compound really keeps, what ruins them on the shelf and how to tell if an old one is still good.
O-Ring Shelf Life
O-Ring shelf life by compound, certified against SAE ARP5316 and ISO 2230: how long nitrile, Viton, EPDM, silicone, FFKM, urethane and more last on the shelf, how cure dates work, and the storage conditions that make them last. From an ISO 9001:2015 certified distributor.
