The quality of O-rings shipped by HIWIN is defined in accordance with ISO3601 standards (Series G & Grade N);
different brands of Fluor elastomers have different product names, also known as FKM and FPM. It is Viton
®
with DuPont™ from the United States, Dyneon™ with 3M from the United States, and DAI-EL with Daikin
®
from
Japan. If customers need to replace O-rings by themselves, apart from purchasing directly from HIWIN, they can
also contact local suppliers to obtain materials equivalent to Viton. Note that the hardness must be above 70° of
Shore A.
