حلقات O-Ring EPDM 0.139" CS × 1.109" ID | AS568-216 | داش 216 | صلابة 70 | أسود (250 / عبوة)

The 70-durometer material makes these o-rings firm enough to hold a seal in my hot water recirculation pump without deforming, and the -65°F rating gives me confidence for winter use. They fit the groove perfectly on the first try.

I needed a larger batch for a gasketing project and these EPDM rings arrived in good shape. The package count was accurate, and they handled a steam cleaning cycle at around 280°F without any issue. My only small complaint is that the bag could be resealable for easier storage.

I needed a high-temp seal for an outdoor sensor housing and these EPDM rings handled the 300°F range without any issues. The 70 durometer feels just right for getting a good seal without being too stiff, though the package of 250 is more than I'll use in a lifetime.
