حلقات O-Ring من Viton FKM مقاس 0.139 بوصة CS × 3.984 بوصة ID | AS568-242 | داش 242 | متوافق مع FDA | صلابة 60 | أبيض (8 / عبوة)

The high-temp rating was the reason I picked these, and the fact they're FDA compliant sealed it for my application. They seated snugly into the groove without any deformation, and the 60 durometer feels just right for a secure seal.

These white Viton rings feel noticeably firmer than the standard black ones I've used before—the 60 durometer is a nice balance. Installed one on a hot water valve rated near 200°F and it seated perfectly without any distortion. Exactly what I needed for a food-grade application.

Swapped out the old rubber gaskets on our hot water line for these Viton FKM rings, and the 400°F rating gives me real peace of mind. The white 60 durometer material is noticeably firmer than the cheap ones I used before, and they seated perfectly without any tweaking.
