Victoria ★★★★★

I needed these for a hydraulic repair job and the 70 durometer gave just the right amount of firmness without being too stiff. The package of 200 will last me through several more projects, which is a solid value.

Joseph D. ★★★★★

Finally, an o-ring that actually fits the groove without forcing—the 1.6" ID is spot-on. I've used a few of these in a hot water line holding at 180°F and they've stayed soft and sealed for three weeks now. For two hundred of them, the price is a no-brainer.

Daniel I. ★★★★★

The cross-section on these is exactly 0.21", which made them a snug fit in the groove I had measured out. I've used them on a small pneumatic line and they've held pressure perfectly without any leaks so far.
