Orange silicone type sealer in Napolean gas fireplace

[Treacherous]

I had to replace a thermocouple in my gas fireplace, What is the orange silicone sealer used to seal up the wiring connections below the pilot?

Thanks

most likely red high-temp RTV, available at any auto parts store or walmart... I doubt it was an intumescent product....
