David ★★★★★

I needed a reliable seal for a pneumatic cylinder that occasionally runs near 200°F, and these o-rings fit perfectly with a snug inner diameter of 2.234 inches. The 70 durometer feels firm yet flexible enough to seat easily, and the package of 26 was just enough for my project.

Matthew X. ★★★★★

The metal-detectable feature gives me peace of mind in our food processing line, and the 70 durometer feels just right for a snug seal without being too stiff. These arrived well-packaged and have held up perfectly through multiple hot washdown cycles.

Kevin ★★★★★

These hit the exact 2.234" ID I needed for a hydraulic cap, and the metal-detectable feature gives me real peace of mind in our food-grade machinery. The 70 durometer seals nicely without being a chore to install, and the 26-pack means I have spares on hand.
