Elizabeth ★★★★★

Finally found HNBR o-rings that can handle the higher heat near my engine bay without degrading. The 70 durometer feels just right for a snug seal, and the 50-pack should last me through multiple projects.

Harper K. ★★★★★

These are exactly the right dimensions for my dash 212 rebuild, and the 70 durometer feels firm without being brittle when I stretch them into the groove. I've already used a handful for a hydraulic fitting and they seated perfectly, no leaks.

Ellie ★★★★★

These seals fit the dash 212 slot perfectly, and the 70 durometer feels right for the pressure I’m putting on them. I’ve had them in service for a few weeks now, and they’re holding up great in the heat, which is exactly why I switched to HNBR. The pack of 50 means I won’t be hunting for one anytime
