حلقات O من بونا-نايتريل CS 0.103 بوصة × ID 1.424 بوصة | AS568-127 | داش 127 | صلابة 90 (500 / عبوة)

The 90 durometer feels noticeably firmer than standard rings, which was exactly what I needed for a high-pressure hydraulic seal. These fit perfectly into the groove, and the box of 500 should last me years.

Needed a full box of these exact o-rings for a rebuild and the 90 durometer hardness feels properly stiff, not flimsy. The 1.424" ID fits my groove snugly and the quantity means I won't run out mid-project.

I was pleasantly surprised by how tight the fit is with the 90 durometer material—these o-rings seat perfectly in my hydraulic port without any rolling. The 500-pack is a great value for the price, and they've held up well under constant 100 psi pressure for the past month.
