just acquired a Burco C30STHF boiler. Had intended to replace the tap with a lever ball valve connected to a hop strainer made from copper pipe.
However, on removing the tap I found the hole is not round. So as plan B I thought I would replace the 1" nut on the inside with a coupler which would lock the original tap in place and allow me to insert a 22mm copper pipe which I will drill holes into for a hop filter.
I can only find one such coupler which I have linked below. As it is described as iron, would it be food safe?

Thanks for your thoughts.
