حلقات O من HNBR بقطر داخلي 6.359" وقطر مقطع 0.139" | AS568-261 | داش 261 | صلابة 90 (6 / عبوة)

I’ve been using these for high-temp oil seals on a compressor, and the 90 durometer holds up perfectly at 300°F without softening. The HNBR material gives me way more confidence than standard nitrile for this application.

I needed a tough seal for a hydraulic repair and the 90 durometer on these HNBR rings handled the pressure without deforming. They slid into the groove cleanly and the temperature range covers everything I work with.

These o-rings were a perfect fit for a high-temp hydraulic application I've been fighting with. The 90 durometer HNBR is stiff enough to hold pressure at 275°F without any noticeable deformation after a week of service.
