Which Passthrough is this?

[Seventh]

I ordered a 510 passthrough, and while it looks the part, it's threaded incorrectly to match with my atomizer - it should be a female end, and what I have is a male end - and all my atty's have the same end on them.

Is this not a 510 PT, am I missing a piece, or am I overlooking something completely ridiculous?

It looks to me like a KR808. The 510 has female threads, the KR808 has male threads like yours. If I'm correct you should be able to use the KR808 cartomizers or a 901 atomizer on it.

Aha! Thank you!
