حلقات O من Viton FKM | AS568-160 | داش 160 | صلابة 75 | أسود (18 / عبوة)

Used these to replace old gaskets in a chemical pump that was leaking, and they're holding up perfectly even at 350°F. The 75 durometer rubber feels firm enough to seal tight without being too hard to work into the groove.

Needed a seal that could handle extreme temps without degrading, and these Viton FKM rings performed perfectly on a steam line repair. The 75 durometer hardness gave just the right compression without being too stiff.

Used these in a high-heat hydraulic system that hits around 350°F, and they've held up perfectly with no sign of hardening or cracking. The 75 durometer feels just right for a seal that doesn't squirm under pressure. Exactly what I needed for a tough application.
