Lucy ★★★★★

The 75 durometer hardness feels just right for a snug seal, and the brown color makes them easy to spot during assembly. I've been running these in a heat cycling setup and the -15°F to +400°F range gives me real peace of mind.

Jacob J. ★★★★★

Used a few in a high-temp compressor application and they sealed without any issues, even after repeated heat cycles. The brown color makes them easy to spot against dark metal surfaces, which is a nice bonus.

Sebastian F. ★★★★★

I needed a solid seal for a high-temp hydraulic application, and these -15°F to +400°F rated Viton rings fit perfectly. The 3.239" ID matched my groove precisely, and the brown color makes them easy to spot during assembly.
