حلقات O من Viton FKM | AS568-455 | داش 455 | صلابة 75 | بنية (3 / عبوة)

These handle the heat exactly as rated, I've had them on a hot oil line for two weeks and they haven't softened or swollen at all. The 75 durometer feel is firm but they seat into the groove without fighting you, and the brown color actually makes them easy to spot during inspection.

Finally got these for a high-temp pneumatic seal I was struggling with. The 75 durometer feels substantially stiffer than the standard Buna-N I was using, and they slid right into the groove. Pack of 3 is perfect for a small repair kit.

I’ve been using these in my hot oil system and the 75 durometer is just right—firm enough to seal without cracking. The brown color makes them easy to spot during maintenance.
