Victoria P. ★★★★★

Had to replace a set of old seals in a high-temp pneumatic actuator, and these Viton o-rings handled the 350°F cycling without any issues. The 75 durometer feels just right for a snug fit, and the 85-pack gives plenty of spares for the price.

Evelyn G. ★★★★★

The 75 durometer feels sturdy and not too hard—just right for sealing a hydraulic fitting I repaired. The package of 85 will last me years.

Samuel ★★★★★

The high-temp rating up to 400°F is exactly what I needed for a compressor seal, and they seat perfectly without any leaking. This pack of 85 should last me through several rebuilds.
