Are there different Flow Control knobs, the one bought from you last week does not fit onto the spline of the regulator (flow control knob is smaller I/D than the regulator O/D

There shouldn't be any problems with the control knobs they have been the same for many years and up to this point we haven't had any complaints.

There is a nylon bush in the middle of the knob that goes between the fine brass splines and the coarser teeth on the knob perhaps if your were drop the bush into a cup of hot water for a couple of minutes then push it on to the splines this will solve the problem.

Ultimately we can replace it but I have just cjecked with our stock in the warehouse and they all look OK to me.
