Eva Q. ★★★★★

These handle the heat range perfectly for my high-temp application, and the 75 durometer gives them just the right firmness for a solid seal. The 0.974" ID fit my groove exactly, no struggling to get them seated. Good to have a full hundred pack on hand for future swaps.

Andrew R. ★★★★★

I needed a precise fit for a hydraulic seal and these Dash 318 rings were spot-on. The 75 durometer feels sturdy, and they've held up perfectly under constant heat.

Charlotte ★★★★★

Bought these for a high-temp application where regular o-rings kept failing. The -15°F to +400°F range is exactly what I needed, and they sealed perfectly on the first try.
