Customer Reviews (4.8 / 5 · 5 reviews)

Lucy J. ★★★★★

These are a perfect fit for the hydraulic cylinders on my press, and the 70 durometer feels like a solid, durable rubber. The 2.236" ID matched exactly what I needed, so no struggling to get them seated.

Eva C. ★★★★★

I replaced the old o-rings on my pneumatic actuator with these AS568-140s and the fit was perfect. The 70 durometer rubber feels durable and should handle the temperature swings in my shop just fine.

Timothy Q. ★★★★★

These handled the hydraulic fluid on my log splitter perfectly, and the 70 durometer feels firm enough that I don't worry about them squishing out of the groove. The 2.236" ID was a dead-on match for the cylinder cap I needed to reseal, and I still have hundreds left for future jobs.
