Original equipment Corny kegs were intended to be kept at fairly high pressure compared to what is needed for beer.
You may have noticed that at 5 to 10 psi (barely enough pressure to dispense), keg lids leak gas.
Fatter, softer o-rings are available that provide a better seal and don’t depend on keg pressure to keep lids gas tight.
Check out the selection with us.
To stop leaks quickly, momentarily increase the pressure in the keg. Then decrease the pressure slowly.
