حلقات O من السيليكون | AS568-413 | داش 413 | متوافق مع FDA | صلابة 70 ديرومتر | أحمر (12 / عبوة)

Swapping out the old gaskets on my home brewery equipment, these red silicone rings seated perfectly and haven't leaked a drop since. The 70 durometer feels solid, and knowing they're FDA compliant gives me peace of mind.

These red rings feel surprisingly sturdy for the price, and the 70 durometer has held up fine under a few different fittings I’ve tried them on. The -80°F to +450°F spec is the reason I grabbed them, and so far they’ve shown no signs of wear near the heat source.

Needed a high-temp seal for a hot water valve I was rebuilding, and these red silicone rings handled the 200°F steam without any issue. The 70 durometer feels flexible but firm enough to keep a good compression seal.
