Scarlett U. ★★★★★

The 1.296" inner diameter seated perfectly on my hydraulic cylinder’s gland, and the 70 durometer gives just enough give for a snug seal without squishing out. I’ve got 500 on hand for spares, and the -40°F rating means my outdoor equipment should be fine through winter.

Christopher O. ★★★★★

Saved my rebuild of an old air compressor — these 219 o-rings seated perfectly in the cylinder head and haven't leaked a drop after a dozen cycles. The 70 durometer feels just right for the pressure.

Miles H. ★★★★★

I needed a batch of AS568-219 o-rings for a hydraulic repair and these fit the groove perfectly. The 70 durometer feels just right for the application, and the price for a 500-pack is hard to beat.
