510 thread battery "coupler" stripped. Need help with replacement.

[va1mar]

So, those are the pictures of my battery, and or setup.
1st image is the battery components, 2nd is with the "coupler" attached, 3rd is with the "coupler" off, and 4th is the whole setup.
The middle item of the 1st picture is the part that is stripped.
The tank used to fit just fine on it before, but recently stopped.
To be certain I tried my tank on another 510 battery, (not mine) and it worked just fine, but their tank did not work on my battery.
Does anybody know the official part name and where I might procure said part for a reasonable price?
I'm pretty new to the whole vaping scene, and bought my setup from an ebay dealer quite a while ago, so the listing is gone.

Not sure, but i think what your looking for is an ego to 510 adapter. Toss it into Google and i think you'll find what you want.

Sorry, but that thing looks so proprietary I have no idea where you could find the right replacement part to fix it. It might be using some sort of 510/510 female/female coupler but I really can't say with any certainty and that isn't a standard part.
