حلقات O من مطاط النتريل بونا-N | AS568-903 | داش 903 | صلابة 90 (1500 / عبوة)

I was worried the 90 durometer would feel too stiff, but these actually seated perfectly in my hydraulic application. The temperature range down to -40°F gives me peace of mind.

These 90 durometer rings are handling the higher pressure in my pneumatic system without any sign of extrusion. The -40°F lower limit gives me peace of mind for cold weather operation.

Ordered these for a rebuild job and the 90 durometer feels noticeably stiffer than the cheap 70s I had before, which is exactly what I wanted. The -40°F to +250°F range gives me confidence they’ll hold up in my hydraulic lines. 1500 in a bag means I won’t be running out anytime soon.
