حلقات O من فيتون FKM | 0.139 بوصة CS × 0.484 بوصة ID | AS568-206 | داش 206 | صلابة 90 (250 / عبوة)

Used a handful for a high-temp hydraulic repair and they seated perfectly without any deformation. The -15°F to 400°F range is exactly what I needed for this application.

These 90-durometer rings are noticeably firmer than standard Buna-N ones, which made them perfect for a high-temp compressor fitting that kept failing. The 250-count box should last me years, and for the price per ring it’s a no-brainer.

I’ve been using these Viton FKM o-rings in a high-temp pneumatic setup for a few weeks now. The 90 Durometer handles the pressure well, and they seat perfectly in the groove—seems like a solid deal for a bulk pack.
