حلقات O من بونا-ن نيترايل | CS 0.103 بوصة × ID 0.924 بوصة | AS568-119 | داش 119 | صلابة 90 (700/عبوة)

Put a set of these dash 119s on a hydraulic fitting that had been weeping for months, and the 90 durometer material finally stopped the leak. The 0.103" cross-section feels noticeably thicker and more durable than the softer o-rings I usually grab.

The 90 durometer o-rings fit snugly in my hydraulic fittings without any deformation, even after a few hours at 200°F. I bought the 700-pack for a large rebuild project, and the consistent size across the batch saved me from having to reorder.

For a high-pressure hydraulic application I was worried about finding the exact right o-ring, but the 90 durometer on these AS568-119s is perfect. They fit the groove precisely and the nitrile material feels durable even at the upper end of the temperature range.
