Engine oil filter adapter/nipple stripped

So I was given the wrong oil filter and didnt realize it until it was too late, the oil filter adapter/nipple that you screw the oil filter onto is stripped out.

I removed the adapter, it is a hollow screw with male threads on both end. The first couple of threads are messed up.

Does anyone know where to find one of these? I cant find it at any parts store/online/junkyards. Even at the dealership it is discontinued part number 53020098

OR does anyone know the thread count/pitch, I can probably find a generic version.
I'm also wondering if a 2.5l or 4.0 90' bend adapter would fit it, as those are more common even though they are more expensive.

Thanks for the help, it is just sitting in the garage until I can come up with this little part

It's a pipe threaded nipple. Go to the plumbing section at Home Depot or equivalent and bring oil filter and look for one and check the threads.

Best I got but that is what I would do.

Be careful if you go to a hardware store for a nipple. they are npt threads which means they have a taper to the so that the deeper you go, the tighter the fit.
you can clean the last few threads of the existing nipple with a small file if you are patient. Use the old oil filter to test the fit as you do the repair. You could also take the adaptor to a belt sander, you will remove the last 2 threads by turning the adaptor on about a 45 deg. angle as the sander is running. all you are doing is removing the bad threads and giving the filter the ability to get to new clean threads. Again, use the old filter to test so you do not mess up another filter.

Your right about it being 20x1.5mm, but that IS NOT a pipe tread that i know of, it may be some metric tubing.

If there is enough thread left remove the outer part as said before.

Better would be to trim it on a lathe, or re-catch the tread and re-cut it.

Just use a Die nut then clean them up with a file.

It's not a pipe thread I had to actually look. I've been lucky and never had to replace one.

But I did ask at the local NAOA and my Jeep dude has them at the warehouse.
