Fitting new radiator

[Shottsguy22]

I'm have trouble fitting a new radiator. The fitting a won't come off the old one and I've spent a fortune on parts which are wrong. I have the pipes coming through the floor, all I need are the correct fittings for both sides at the bottom of the radiator. The lower left is 15mm and the lower right has a trv which is 10mm. Does anyone know the fittings I need to use? The fittings need to be 15mm coming out of the radiator and 10mm at the other end at trv.

I've added photos to my album to show you both sides and the parts that were on the old radiator

Are you fitting a new radiator with new valves or keeping the existing valves?
Not sure why you need 15mm at one side and 10mm at the other are you sure about this?

You can get differently sized rad tails.

But these tails normally come with the valves.
Some will require a rad key/spanner to fit.

On the right hand side rad fitting, you can see flats on the chrome pipe between the nut and the rad. Put a spanner on there to turn the fitting anti-clockwise out of the rad.

Not sure if there are flats on the left one, but you can see where a rad wrench fits the hex/octagonal flats if you look inside the open end of fitting.

When you get the old fittings out, you will need to clean old PTFE tape off of end of the fittings and put about 10 turns of new tape on them. Wind the PTFE clockwise, viewing the fitting from the threaded end that screws into rad.

I'm keeping the pipes that come from the floor. The valves are on them it's just the fitting from the new radiator I need to buy. One side has 15mm pipe and the trv side is 10mm dunno why ? So I need fittings for both sides I've added photos of the old fittings

You don't need new fittings. They'll be tight, but will definitely unscrew and are reusable.

You should be able to remove both the valve tails from the radiator. But I cannot see where you have differing valve tail diameters.
Like linked you may require the rad spanner/key to remove them. Personally would put new valve tails and valves on.

Thanks everyone ! Managed to borrow a radiator key and brute force got it off. Also got the other one off! For future reference can you tell me what they are called incase I need them? Dunno what the 15mm to 10mm one is all about but all my family have them ?!
