How to seal low coolant sensor ,2000 Buick regal?

I have a 2000 Buick regal that I recently had to replace the radiator with a new one. When I removed the old low coolant sensor the o-rings on it were smashed flat and it would not seal in the new radiator. I bought a new low coolant sensor and it seemed to seal fine. About a week later it is leaking at the low coolant sensor again, is there anything I can seal it with? (even if it may be a little redneck, I’m good with that)
thanks
