Jacob ★★★★★

I needed replacements for some high-temp seals in a steam valve, and these Viton o-rings fit the AS568-133 spec perfectly. The 90 durometer feels firm but still seals nicely against the metal surface. So far they're holding up great at 350°F without any deformation.

Penelope ★★★★★

These 90-durometer Viton rings handled a hot oil leak in my hydraulic press that had ruined cheaper nitrile seals before. The 1.799" ID fit the groove perfectly on the first try, and the whole pack of 80 means I've got spares for the next rebuild.

Robert ★★★★★

Needed a reliable seal for a high-temp line that peaks around 350°F, and these Viton rings have held up without a single leak after a week of cycling. The 1.799" inner diameter fit the groove exactly, no stretching or distortion. At 90 durometer they feel firm but still seated easily.
