Lucy ★★★★★

These o-rings fit perfectly on my pump's cylinder head, and the 90 durometer holds up well under higher pressure without deforming. For the price of a 250-count pack, it's a solid value for any maintenance stock.

Lucy ★★★★★

Ordered a pack of 250 for a rebuild job and the 90 durometer stiffness is just right for the high-pressure seals I needed. The 2.736" ID fit my groove perfectly with no rolling or pinching during install. These will definitely last through the -40°F to +250°F range we deal with in the shop.

Ruby ★★★★★

The 90-durometer hardness is exactly what I needed for a high-pressure seal, and the batch came with zero visible defects across all 250. I’ve already used a dozen on a hydraulic fitting and they seated without any trimming or fighting. This pack will last me years.
