When you Gas Cylinder is leaking from the Valve Area

1      Leakage of gas from the sides of the valve -where the valve is fastened into the cylinder via its threading, can’t be stopped permanently by the application of glue or similar adhesives to the leaking points, from the outside.

 To put a permanent stop to the leakage, a competent gas technician needs to remove the cylinder’s valve entirely, applying thread tape and gasket marker to it before fastening it back into the cylinder.

If acetylene or oxygen gas fire was used to remove the valve, then it cannot be reused and most be replaced.

 When the leakage is from inside the valve itself - like it happens when the burner of a filled camp gas(3kg, 5kg, 6kg and sometimes 12.5kg cylinder) or when the gas regulator of a filled standard 12.5kg cylinder is removed and gas vapor escapes into the atmosphere continuously, the valve simply needs to be replaced by a competent gas technician.

 Applying glue to such as valve is an exercise in futility.
