حلقات O من السيليكون 0.139 بوصة CS × 5.859 بوصة ID | AS568-257 | داش 257 | قابلة للكشف المعدني | صلابة 70 (6/عبوة)

My lab runs hot processes up to 400°F and these held up without any softening or warping across repeated cycles. The metal-detectable feature gives us peace of mind for food-adjacent equipment, and the 70 durometer feels just right for a snug seal. Ordering the six-pack was the right call for spares

These metal-detectable rings fit perfectly on our mixing vat lid, and the 70 durometer feels just right—not too stiff, not too soft. The -80°F to +450°F range gives me confidence for both hot and cold processes.

The high-temperature rating is exactly what I needed for my application near a heat source, and the fit on the 5.859" ID was spot-on. These metal-detectable rings give me real peace of mind in the food processing line.
