    Hi,

    Can anyone tell what the aquarium CO2 tank connector thread standard used in Singapore? It seems like it is not the US standard CGA320. I have a regulator fitted with CGA320 (claimed by the manufacturer) but could not fit onto all my 3 different volume size CO2 tanks in Singapore (1L, 2L, 5L).

    Any one has any clue on this , and what is it called and according to what standard ?

    Thanks in advance.

    Cheers

    Just checked with Sing Swee Bee salesman. Confirmed common CO2 tanks used in Singapore are British Standard BS341 . USA is using CGA 320.

    So be careful if you are ordering /importing any regulator or CO2 tank from oversea.

    Cheers

    Re: What is the CO2 tank connector standard used in Singapore

    Hi there! I'm planning to buy a CO2 regulator online & there was an inlet thread option between G5/8, W12.8 or M22. Was wondering if anyone here have had any experience buying online & which thread should I choose that is compatible with CO2 cylinders here in Singapore.
    Or the issue isn't that simple as the cylinders sold here have diff. threads too?
    Any insight would be very much appreciated.

    p.s. I do know that there are adaptors from one type of threading to another. I guess I would prefer not to have the adaptors if I can.
