حلقات O من بونا-N نيترايل | CS 0.139" × ID 7.234" | AS568-265 | داش 265 | صلادة 70 | أسود (50/عبوة)

Swapped these into a hydraulic line that runs hot all day and they’ve held up without any softening or deformation, which is exactly what I needed from the 250°F rating. The 70 durometer feel is stiff enough to seat firmly but still easy to work into the groove.

The 7.234" inner diameter fit perfectly on my air compressor filter housing, and the 70 durometer rubber feels dense enough to handle the 100 psi without any leaks.

The cross-section on these o-rings is exactly 0.139" as listed, and they fit snugly in my hydraulic repair job. The 70 durometer feels just right for the compression needed.
