Chloe X. ★★★★★

The 1.287" ID fit perfectly on my pneumatic cylinder where the old ones kept failing. These 70 durometer rings feel firm and durable, and the 100-pack gives me plenty of spares for future repairs.

Christopher R. ★★★★★

My current project needed seals that could handle some serious heat cycling, and these EPDM o-rings with their -65°F to +300°F range have been flawless in the test rig so far. The 70 durometer gives them a nice, firm feel without being too stiff to install.

Miles ★★★★★

The 0.21" cross-section fits perfectly into my pneumatic valve, and the EPDM material handles the heat from nearby components without any issues. I’ve ordered these before and they seal just as well as the last batch.
