Look well made, lots of applications
These o-ring gaskets are good for lots of applications including quite a few make/model oil pans that call for m14 rubber o-rings. Measurements I show with my caliper are: 13mm ID x 22mm OD x 2.4mm thickness. Looking with my magnifying light I can't see any defects.If I get any leakage I will return to edit my review to reflect that.

Exactly what I needed
Recently changed oil and it seems the nylon washer finally gave out. I cam back to a pool of oil on the ground. Ordered these and had to quickly swap out the old for the new. Total mess but not leaking any longer. Will swap out the washers every few oil changes now as a precaution.
