Aurora E. ★★★★★

Installed these in a high-temp pump that's been eating standard Buna-N rings. The Viton FKM handles the 350°F operating temperature without any sign of hardening. Exactly what I needed for that application.

Richard W. ★★★★★

These seals slid right into the hydraulic cylinder on my press and stopped the slow leak I’d been dealing with. The Viton compound handles the 350°F operating heat without any softening or deformation.

Timothy ★★★★★

Finally got around to replacing the worn seals on my hydraulic manifold, and this 2.859" ID size dropped right in with zero fuss. The Viton material feels noticeably more substantial than the cheap Buna ones I used before, so I'm not worried about it softening near the hot oil lines.
