Customer Reviews (4.6 / 5 · 5 reviews)

Julian ★★★★★

These are exactly the right size for a rebuild I was doing, and the 70 durometer hardness feels solid and durable. I like that they can handle the 250 degree range since my setup gets pretty hot.

Grace G. ★★★★★

I needed to replace some seals in a hydraulic fitting, and the 70 durometer on these AS568-459 rings felt just right—stiff enough to hold pressure but not brittle. They slid in easily and seated perfectly without any trimming needed.

Adam V. ★★★★★

These o-rings were exactly the right size for my project, and the 70 durometer feels solid without being too stiff. I’m glad they can handle temperatures down to -40°F, since my application sees some cold weather.
