Your review: I work on gas fireplaces and these thermocouples have saved me in field many times. Many of my customers have their gas fireplaces working tonight because of these. I bought 10 at first and used them all in about 5 weeks. So I ordered 30 of them this time.
They don't fit perfectly in every application but I manage to make them stay in place by bending the copper conduit in such a way that they don'r move.
I am very happy with these and I will buy many more of these in the years ahead from Global Ind.
