Morning. I have this connection to make, between 35mm copper pipe and a big Grundfos pump. The official Grundfos connector is this iron 1/14 bsp female. The brass adapter I've got screws in, too tight to do by hand but smoothly with a spanner. There's no mating face though, and it's a parallel thread. Will it seal, do you think, in a heating system, and if so what sealant would you use? Any advice gratefully received!
