0.139" CS × 5.234" ID حلقات O من Viton FKM | AS568-252 | داش 252 | X-Ring | صلابة 70 (6 / عبوة)

I needed an o-ring that could survive 400°F near my engine, and this Viton FKM version handles it without breaking a sweat. The 5.234-inch inner diameter fit perfectly on my application, and the 70-durometer material feels solid.

Finally found o-rings that can handle the 400°F limit my compressor needs; the 70 durometer feels solid and not brittle. These Viton ones are exactly the right size for the seal and should last much longer than standard rubber.

These fit perfectly on my high-temp air line fitting where standard Buna-N rings kept failing. The Viton FKM material handles the 200°F operating temperature without any issue.
