حلقات O من HNBR بقطر داخلي 1.984" وقطر مقطع 0.139" | AS568-226 | داش 226 | صلابة 80 (30 / عبوة)

Used these to replace some worn o-rings on a pneumatic cylinder, and the -40°F rating gave me confidence for our cold storage area. The 80 durometer feels noticeably firmer than the old ones, and the fit was spot on.

Had a small leak in a hydraulic fitting and these HNBR rings stopped it cold. The -40 to 300 degree range gives me confidence they'll handle the hot oil just fine.

These 30 o-rings fit perfectly into my hydraulic pump rebuild; the 80 durometer feels noticeably firmer than the cheaper ones I've tried before. The -40°F to 300°F rating gives me confidence they'll hold up in my unheated shop during the winter.
