Supercedes to 10-2608.
This is the genuine, original equipment (OEM) oil pan drain plug o-ring. While copper crush washers like these are excellent for sealing, they are one time use items that must be replaced each time the drain plug is loosened. Sold individually; one required per car.
This part number is “superceded”. Most of our supercessions originated with Nissan. A part made for a Z31, for instance, may actually be the same as the part made for the Z32, but it was given a different number. Nissan would then later supercede the number, so that if you ordered the part number for the Z32, what you would actually get is the original part number for the Z31 (or vice-versa), as they are the same part. Other times, supercessions can exist between different parts on the same car, as is often the case with hardware of the same size. These supercessions were Nissan decisions, where replacing the “superceded from” part with the “superceded to” part results in identical performance. The vast majority of them are simple numbering changes, where the parts are literally identical. In some cases, the two parts are identical in fit and function, but the finish is slightly different, or the non-critical overall dimensions are slightly different (like one starter housing being Ľ” shorter than the other on the non-attached side). They do not affect the function of the part, and in many cases, the “superceded-to” part improves upon the “superceded-from” part.
