حلقات O من HNBR قطر داخلي 0.674 بوصة × قطر مقطع 0.103 بوصة | AS568-115 | داش 115 | صلابة 90 (80 / عبوة)

The 90 durometer hardness is exactly what I needed for a high-pressure application, and the 0.674" inner diameter fit the groove perfectly on the first try. These seals handle the 300°F service temperature without any softening, and the package of 80 means I've got spares for the next few rebuilds.

I needed a 90-durometer seal for my hydraulics setup, and these HNBR rings handle the 300°F heat limit exactly as specified. The 0.674" ID sits snugly without distortion.

The 90 durometer feels just right for high-temp applications, and the -115 size fit perfectly on my press fitting. They seal nicely even at sustained 250°F, exactly what I needed.
