Adam D. ★★★★★

The 90 durometer hardness was exactly what I needed for a high-pressure pneumatic cylinder that kept leaking with softer rings. These 123 size o-rings seated perfectly in the groove and have held up through several heat cycles.

George ★★★★★

These replaced a cracked seal in my hydraulic setup and haven’t leaked a drop since. The -40°F to +250°F range covers everything I throw at them, and having 600 in the bag means I’m set for years.

Abigail L. ★★★★★

The 90 Durometer hardness is spot on—these didn’t squish or deform when I seated them in a tight gland, which was my main worry. Having 600 in the bag means I’ve already used a handful for a hydraulic test and have plenty left for the next rebuild. Solid value for the price.
