The bright red color makes them easy to spot on my workbench, which is a nice bonus. I've torqued them down in a hot water line and they hold perfectly at the 450°F rating without any deform. These got my pump back together and sealed on the first try.

I was replacing some worn seals in a brewery fitting and these red silicone o-rings fit perfectly with no leaks. The 70 durometer feels sturdy but still seals well on the first try.

The high-temperature rating is exactly what I needed for my autoclave door — no more melting or deformation after repeated cycles. These rings feel dense and springy, and the red color makes them easy to spot during maintenance.
