Hannah ★★★★★

Finally found a pack of 432s that fit my hydraulic repair kit perfectly—the -40°F rating is a big plus for my cold shop. These Buna-N rings handled the mineral oil without swelling, and the 70 durometer feels pliable but firm. Glad I grabbed these instead of the generic hardware store mix bag.

Sophia F. ★★★★★

The 70 durometer rating is spot-on for my pneumatic actuator rebuild—seals tightly without being too stiff. These dash 432s fit perfectly into the groove and handled the air compressor heat cycle without any issues. Much better than the generic mix pack I was using before.

Victoria ★★★★★

Ordered these for my hydraulic repair kit and they're identical to the OEM replacements I've been buying. The 70 durometer feels just right for the pressure we're running.
