O-ring Hardness (Durometer): 30 durometer; 45 durometer; 50 durometer; 55 durometer; 60 durometer; 70 durometer Synthetic Rubbers: Silicone Rubber; Vinyl, Chloroprene O-ring Size: Available in all ...
Durometers are pushed against the sample to be tested and the hardness information is displayed. This is considered a form of nondestructive testing, as the sample is not permanently deformed.
