Fitting Radiator

I have purchase a new rad, same size as the old one.

Fitted a TRV.

The pipework comes out of the floor, which is a ground floor and have no lateral movement.

The radiator fitted with the couplings is to wide for the existing pipework by about 1/2". I am concerned if I pull the pipe to much I will end up bending it.

What is the best solution, Is it ok to use a flexible.......

Thanks

No. You'll have to put a Z in at least one of the pipes.

put a bending spring down the pipe and you may get a bend if there`s enough sticking out the floor to manipulate
