Japanese Industrial Standard (JIS) O-rings

The Japanese Industrial Standard (JIS B 2401) lists 194 sizes of O-Rings which are unique to Japan's automotive and manufacturing industries. At The O-ring Store we stock these sizes and have them separated into their P, G, V, and S series. They are available in both Buna-N 70 Durometer and Viton (FKM) 75 Durometer.
