حلقات O من السيليكون | AS568-157 | داش 157 | قابلة للكشف المعدني | صلابة 70 (8 / عبوة)

I needed o-rings that could handle extreme temps for a high-heat industrial application, and these silicone ones have held up perfectly at 450°F without any degradation. The 70 durometer gives them just the right firmness for a secure seal.

The metal-detectable feature gives me peace of mind in our food processing line, and the -80°F rating handles our freezer seals without cracking. These eight rings fit perfectly on the dash-157 fittings.

The high-temp range is perfect for my oven gaskets—used them for months without any hardening or cracking. The metal-detectable aspect gives solid peace of mind for food lines. Fits the AS568-157 groove exactly, no stretching needed.
