At pilot light, where pilot light flame goes directly onto thermo coupler.
If you mean the pilot doesn't stay lit, the problem is prabably a faulty thermo coupler.
Most thermocouples just pull out of the pilot assembly, but others have a nut at the bottom that you have to unscrew to remove them.
It will measure the temperature difference between two points and convert it to voltage signal.
You may mean a 'thermocouple' - this is a small metal bulb that sends a signal to the gas regulator that the pilot light is on or off. This is a safety feature that will not allow the gas regulator to open if the pilot light is off.
50% Coupler :D
No, there are 6 different tapping mechanisms. the US Sankey the European Sankey the Bass Ale Coupler the German Coupler the Guinness Coupler and the M-System Coupler
Yes it is a female to female coupler
thermo 1 is the hardest.
