Can someone who does this regularly give me a clue on how you go looking for the industry source of some part or other?

Right now I'm looking for a little heater pad to warm a static port and another one for a fuel vent.  Given it's sitting on resin it should be thermostatically controlled and not enough power to burn a hole.   If I google "heater pad" I get retail parts, none of which do what I want.   I think I want the name of the company, e.g. that makes the pads and thermostats themselves.
