حلقات O من بونا-إن نتريل 0.103 بوصة CS × 1.736 بوصة ID | AS568-132 | داش 132 | صلابة 90 (500 / عبوة)

Ordered these 90 durometer o-rings for a pneumatic repair job and they fit the groove perfectly without any deformation during installation. The -40°F rating gives me confidence they'll handle cold-weather operation just fine.

The 90 durometer hardness is exactly what I needed for a high-pressure seal—these won't deform under load like the softer ones I've tried. The -40°F range is a bonus since my equipment sits in an unheated shed over winter.

I needed a 1.736" ID o-ring for a hydraulic repair job and this pack of 500 is way more than I'll use, but the price per ring is unbeatable. The 90 durometer feels firm and durable, and they seated perfectly into the groove without binding. Solid purchase for anyone working with Buna-N.
