I have the Tunze CO2 Regulator 7077.3 and the seal with the CO2 tank is leaking. It looks like I lost the sealing ring. I cannot seem to locate anywhere on the internet that offers them. Tunze's own website doesn't even recognize the part number shown in the manual. 7077.310_A - sealing ring for CO2 cylinder, US Version (S2). Can anyone offer help for me? Thank you.
 
Take the regulator to Ace hardware and see if they have a ring that fits correctly ..
 
any co2 gas refill carries them in regular or teflon
 
@rvitko may be able to help. The seals for standard co2 regulators may be too stiff to get a seal as they usually need to be wrench tightened whereas the tunze uses a soft seal that seals easily by hand. I would get a spare or two to have on hand. I wouldn’t want to wrench on the knurled tunze coupler (maybe temporarily for an emergency until you can get the right seals).
