Customer Reviews (4.2 / 5 · 5 reviews)

Julian ★★★★★

The high-temp rating sealed it for me—these handle the 350°F heat cycles in my engine bay without deforming. They're firm at 75 durometer, which made installing them a bit snug, but that's exactly what I wanted for a tight seal.

Andrew ★★★★★

Perfect fit for our hydraulic press rebuild—the 75 durometer feels sturdy but still pliable enough to seat easily. Handles the 350°F steam exposure without any sign of hardening after two weeks of daily use.

Emily ★★★★☆

Needed a few of these for a high-temp application and the 75 durometer seems just right — not too stiff, not too soft. The pack of 20 should last me a while for the price.
