Harper ★★★★★

Finally, an o-ring that handles the heat without degrading—the FKM material shrugs off 400°F like nothing. The 4.739" inner diameter seated perfectly in my flange, and the brown color makes it easy to spot during assembly.

Riley H. ★★★★★

The fit is perfect on my hydraulic cylinder rebuild; the 0.07" cross-section feels slightly thicker than the old ones, which should give a better seal. These handled the 400°F rating I needed for the hot oil system with no issues so far.

George ★★★★★

I needed a reliable seal for a high-temp hydraulic setup and these FKM o-rings fit the bill perfectly. The 75 durometer gives them just the right firmness without feeling brittle, and they’ve held up great at 400°F.
