حلقات O-Ring من بونا-إن نيتريل | 0.103" CS × 1.799" ID | AS568-133 | داش 133 | صلابة 50 (200/عبوة)

These o-rings fit perfectly on my hydraulic cylinder caps where I needed a softer seal without over-tightening. The 200-count pack will last me through several rebuild jobs, and the -40°F rating gives me confidence for winter use.

Finally got around to using these AS568-133 o-rings on a hydraulic repair job and they sealed perfectly on the first try. The 50 durometer material feels just right for a snug fit without being too stiff.

I've been through a whole box of these on a hot hydraulic line that sits near an engine block, and at 50 durometer they're soft enough to seat without fighting but still hold up well. The -40 to +250 range covers everything I've thrown at them, and having 200 in the bag means I don't have to reorder
