حلقات O من السيليكون | AS568-452 | داش 452 | متوافقة مع FDA | صلابة 70 | أحمر (6 / عبوة)

I needed a high-temp seal for an oven gasket repair, and these silicone rings fit the groove perfectly at 70 durometer. They've held up well through several 400°F cycles without any cracking or deformation.

These handled the hot water side of my pressure washer setup without a single leak, and the bright red color made them easy to spot during installation. The -80°F to +450°F range gives me plenty of confidence for future steam applications too.

Used these to replace a few ancient seals in my lab's steam line, and they fit perfectly. The 70 durometer feels just right—not too stiff, not too squishy. Pleasantly surprised how well they handle the high heat.
