internal thread cga 320 which model

Photos show option #1 as female cga320 to male w 21.8.

Cga320 (g1/2-14), outer thread: w21.8-14 #1 still is #2

There have 2 type, Type1 is W21.8 convert to CGA320, Type2 is CGA320 convert to W21.8, thanks.

So #1 is for when my tank is w.21 and my regulator is cga 320 ? also is w.21 is like british #8 and din 477 ?

Option #1 appears to be for a cga320 cylinder to a w 21.8 regulator and option #2 looks to be for a w 21.8 cylinder to a cga320 regulator. Also, I think w 21.8 is a DIN 477 #6.

I have a tank with cga 320 and a hose with w21.8 which one so i get so i can hook these up?

Option #1 threads on to a cga320 cylinder (standard carbon dioxide fitting in the U.S.) so that the W 21.8 can be threaded to it.

Clarification on #1 vs #2

Four stars for a poor product description, "converts" means different things to different people.Item #1 is female cga320 and male 21.8-14. Presumably #2 is the opposite.
