are all Russian & Eastern gas mask hoses interchangable? same size?

[bolo]

I was looking for a gas mask hose to fit a Russian Tank Commander Radio Communication gas mask

do all Eastern Block countries gas mask hoses fit Russian gas masks? would a gas mask hose & filter from a East German gas mask fit a Russian gas mask? Im curious if the hoses use the same size threads.

Did the DDR produced their own Masks? I allway's saw the russian or czech Masks in the NVA. But Yes, if they have the Screw Type Hoses, they're interchangeable. Also With BW, WH and lots of others.

All Eastern Block countries that were under russian control used the GOS filter thread, which is essentially the same diameter of the German DIN but with a larger pitch of the screw.

Surely not GOS but GOST - "State Standard"

Comrades,
DDR Hoses tend to be black rubber, Soviet one's tend to be covered with a blue/grey stockinet material.

Purely defensive, Progressive hoses will fit on reactionary, inferior, first strike lunatic schemed NATO weapon of Mass Destruction Respirator Canisters.
