Zoe ★★★★★

The 70 durometer is just right for my pneumatic fittings—firm enough to seal tightly without being impossible to squeeze into place. I bought the 250-pack and it's nice having spares on hand for future projects. Service temperature range gives me confidence they'll hold up in my heated garage.

Evelyn ★★★★★

I’ve been using these neoprene o-rings for a few weeks and they seal perfectly in my pneumatic fittings; the -45°F to +250°F temperature range gives me confidence they’ll hold up in my shop. The 250-pack is great value for the size.

Jason ★★★★★

The neoprene material seems more flexible than the Buna-N ones I usually use, they seat nicely in the groove. Got these for a low-pressure water application and they sealed perfectly on the first try. For 250 pieces at this price it's a solid value.
