Customer Reviews (4.8 / 5 · 5 reviews)

Owen D. ★★★★★

Installed these on a hot oil circulation pump that kept leaking with standard Buna-Ns. The Viton material handled the 350°F operating temperature without any softening or deformation.

Mia ★★★★★

Took a chance on these for a high-temp pneumatic valve rebuild, and the -15°F to +400°F range covers everything I need. The brown color makes them easy to spot against the metal fittings during install.

Joshua M. ★★★★★

Used one on a hydraulic fitting that sees constant 350°F oil, and it's held perfectly for three weeks now with zero leaks. The 75 durometer gives it just the right stiffness without being brittle to install.
