حلقات EPDM دائرية 0.103 بوصة CS × 0.549 بوصة ID | AS568-113 | داش 113 | صلابة 70 | أسود (600/عبوة)

Needed to replace some old gaskets in a hydraulic fitting, and these 70-durometer EPDM rings sealed it up tight with no leaks at the 300°F operating range. The pack of 600 means I’ve got spares for the next few projects.

The -65°F to +300°F range is what sold me, and after a hot summer and a freezing garage install, they've held up perfectly in both extremes. The 70 durometer hardness gives just enough squish without feeling flimsy when I seat them in the groove.

These seal perfectly on my heated coolant lines where the silicone ones kept degrading. I've had them in service for six months now with no leaks, and the -65°F rating gives me confidence for winter operation.
