حلقات O من السيليكون 0.139" CS X 2.359" ID | AS568-229 | داش 229 | قابلة للكشف بالمعادن | صلابة 70 (11 / عبوة)

Used these to replace a worn gasket on a high-temp pump at work; they fit perfectly and the -80°F to +450°F range covers everything we throw at them. The 70 durometer feels just right—firm enough to seal but not too stiff to install easily.

The temperature range is what sold me—these handle way hotter conditions than the cheap rubber ones I was using. The metal-detectable feature is a nice safety bonus for food equipment, and the 70 durometer stiffness feels just right for a snug seal.

Finally got these to replace some standard o-rings on a high-temp valve, and the -80°F to +450°F range is exactly what I needed. They seated perfectly on the first try with no distortion.
