حلقات O من السيليكون | AS568-165 | داش 165 | متوافقة مع FDA | صلابة 70 | أحمر (24/عبوة)

I use these in a high-heat application where my old ones kept melting, and the 450°F rating has been a lifesaver. The red color makes them easy to spot during maintenance checks.

I needed a silicone replacement for a lab fitting that sees steam, and these o-rings are soft enough to seat perfectly while staying rigid where it counts. The red color makes them easy to spot during assembly, and the 24-pack gives plenty of spares for future maintenance.

These seals handled the heat in my oven's steam tray perfectly, no softening or warping at over 400°F. The 70 durometer gives them a nice firm feel without being too stiff to seat easily in the groove. Exactly what I needed for a high-temp food application.
