حلقات O من مطاط النتريل بونا-N | AS568-468 | داش 468 | صلابة 70 | أسود (8 / عبوة)

Had to dig through my parts bin for some bigger o-rings and these AS568-468s in 70 durometer fit the bill exactly, the temperature range down to -40°F is a nice buffer for my outdoor equipment. The black nitrile material feels sturdy and these should hold up fine.

The 70 durometer hardness is perfect for my air fitting repairs, holding a solid seal under the compressor's vibration. These dash 468 rings fit precisely and feel noticeably tougher than the generic ones I used before.

Had a small leak on my hydraulic cylinder and these dash 468s fit perfectly—sealed tight on the first try. The 70 durometer feels exactly right for this application.
