Does this work for the jt er2 pump pistol rts kit

The ones I am selling are standard size. So I think they are universal fit. If you want to try them out, if they don't fit you can send them back to me for refund.

No, the ones i'm selling aren't threaded.

Will these cartridges fit a Umerex BB pistol?

I used them for my Umarex SA.177 Co2 gun. There a specification for "grams" that your BB gun uses. I beleive these your asking about are 12 grams which relates to size and pressure.

is it 12 Grams per cartridge, or 1.2 per cartridge?

Each cartridge holds 12 grams of liquid CO2. Be sure to select Paintball Discounters as your Amazon fulfillment partner.
