حلقات O من مطاط بونا-إن نيتريل | AS568-152 | داش 152 | صلادة 70 | أسود (250 / عبوة)

Used these AS568-152 o-rings to fix a stubborn hydraulic leak on my tractor. The 70 durometer material feels firm but flexible enough to seat perfectly in the groove. Fit exactly as expected and the whole package of 250 should last me years.

Finally got around to sealing the coolant lines on my lathe and these 152s fit the grooves perfectly. The 70 durometer feels firm but not brittle, and knowing they handle up to 250°F gives me peace of mind since that's right around where my system runs. 250 in a bag means I've got spares for the nex

Got these for a standard job and they seated fine. The -40°F to +250°F range covers what I needed, though the 250-pack is more than I'll use for a while.
