which 'looks' very like the type used in gas fires and similar to those used in gas boilers:

I'm fitting the burner into a shroud and want to reposition the thermocouple on the inside of the ring, but to do so I'd need one with a slightly longer 'lead'. I can work out if the threads/fittings match, but does anyone know if the gas fire or boiler types are likely to be functionally compatible? I don't know if all these things are more or less the same or not.
