Zoe ★★★★★

Finally got around to using these HNBR o-rings on a high-temp oil line, and they seated perfectly without any deformation. The 80 durometer feels just right for a snug, leak-free seal. Happy with the 70 pack for the price.

Chloe L. ★★★★★

The 80 durometer hardness is perfect for my application where I needed a seal that wouldn’t squish out under pressure. These HNBR rings held up fine after a few heat cycles up to 200°F in a pneumatic system.

Brian Y. ★★★★★

Bought a pack of these for a hydraulic repair and the 80 durometer hardness sealed perfectly on the first try, no leaks. The sizing is dead-on and they handle the heat range I need for my shop equipment.
