Customer Reviews (4.8 / 5 · 5 reviews)

Riley ★★★★★

These handled the -40°F service range easily in my unheated shop, no cracking or hardening after a full winter. The 70-durometer stiffness feels just right for a snug seal on the 2.736" bore, and the pack of 250 means I’ve got spares for years.

Chloe ★★★★★

The 0.103" cross-section feels substantial and the 70 durometer hardness is perfect for my pneumatic application where a softer ring would squirm. The temperature range covers my system's hot end nicely, which is exactly why I chose nitrile over a cheaper material.

Ella ★★★★★

I needed a batch of 148 o-rings to reseal a pneumatic actuator, and the 70 durometer material held up perfectly during the test cycle. These fit the groove snugly and the bag was packed full.
