Customer Reviews (4.4 / 5 · 5 reviews)

Nicholas ★★★★★

These o-rings sealed a stubborn hydraulic leak on my tractor pump on the first try, no tweaking needed. The 90 durometer feels noticeably stiffer than standard Buna-N, which is exactly what I needed for the 400°F exhaust manifold area.

Adam ★★★★★

Finally, a proper 2.359" ID fitting for my hydraulic rebuilds—the 90 durometer Viton feels plenty rigid while still seating easily into the groove. I used a handful today on a hot oil line and they handled the 400°F range without issue. Ordering another pack for next month's job.

Isabella ★★★★☆

I've used these for high-temp hydraulic seals and the -15°F to +400°F range covers what I need, though the 90 durometer makes them a bit stiffer to install than softer rings. The pack of 60 is solid value for the price, and they've held up well so far.
