حلقات O من بونا-إن نيتريل CS 0.139 بوصة × ID 1.484 بوصة | AS568-222 | داش 222 | صلابة 90 (400 / عبوة)

I needed a batch of these for a hydraulic repair and the 90 durometer feels just right, not too soft. They slid on easily with a bit of lubricant and held pressure perfectly during testing.

These 90 durometer rings are noticeably stiffer than the standard ones I've used, which is exactly what I needed for a higher-pressure application. The -40° to 250° range gives me confidence they'll hold up in our outdoor machinery. Packed well and the 400 count means I have spares for the next job.

I had to swap out a leaking seal on a hydraulic fitting and these 90 durometer rings are noticeably stiffer than the softer ones I usually grab. The 1.484" inner diameter matched up perfectly and the box of 400 will last me years.
