حلقات دائرية من مطاط بونا-نايتريل | AS568-902 | داش 902 | صلابة 90 (1500/عبوة)

I’ve been using these 90 durometer Buna-N o-rings for a few weeks now in a hydraulic fitting that sees a fair amount of heat, and they’ve held up perfectly without any swelling or cracking. The temperature range they cover is exactly what I needed for that application.
