Jacob ★★★★★

The 0.103" cross-section was a perfect fit for my hydraulic manifold, sealing up a stubborn leak on the first try. I've had issues with other o-rings hardening in heat, but these Viton ones hold up well at 400°F.

Benjamin ★★★★★

The -15°F to +400°F range is exactly what I needed for a hot oil line that kept cooking cheaper rubber. These Viton rings slid on without any twisting and the brown color makes them easy to spot during assembly. Fit the groove perfectly on the first try, no forcing required.

Emma ★★★★★

I ordered these for a hydraulic repair on an older machine and the 0.103" cross-section fit the groove perfectly. The brown color and 75 durometer feel just like the OEM part, and the Viton material should handle the 350°F operating temperature without issue.
