Owen U. ★★★★★

I needed a high-temp seal for a steam valve, and these red silicone rings handled 400°F without any softening or deformation. The 70 durometer feels just right—firm enough to hold pressure but pliable enough to seat easily. A full pack of 55 gives me spares for the next few rebuilds.

Henry ★★★★★

These fit perfectly on my filter housing, and the 70 durometer is firm enough to hold a good seal without being a struggle to install. Handled a hot steam cleaning cycle without any issues, so that temperature range is no joke.

Nicholas A. ★★★★★

The red color makes them easy to spot during installation, and the 70 durometer silicone feels durable. They sealed perfectly on my pump housing after the old ones failed.
