Lucy ★★★★★

The 70 durometer feels just right for the hydraulic fittings on my press, and having two hundred in a bag means I won't run out mid-job. The -40°F temp rating gives me confidence for winter use in the unheated shop.

Emily ★★★★★

I needed a bulk pack for my pneumatic cylinders, and these fit perfectly with the 0.139" cross-section. The -40°F temp rating gives me confidence for outdoor equipment.

Stella R. ★★★★★

The 70 durometer is exactly what I needed for a tight compression fit in a hydraulic valve rebuild. The package of 200 o-rings arrived neatly organized and the material feels durable and pliable, not brittle like some other nitrile I’ve used.
