Hi All,

Just after some quick help please. I've hung a new radiator on the wall and it's got some plastic plugs in the connection points for the valves. They look like they've been powder coated over and when I try to undo them with a screwdriver, they're just rounding off.

Does anyone know how I can remove them? I'm a bit cautious about trying to drill them out.

Thanks in advance

Pair of mole grips or pump pliers normally moves them without damaging the thread.

Thanks both, ended up driving a pair of pliers through the cap to remove it.

Is this how most threads are protected on radiators when they're painted? I've rebuilt a few motorbikes in the past and protected threads with rubber caps or bungs when they've been powder coated. Never had that much hassle removing one!

some are screwed in and some are just bungs that are pushed in , as you sat when they paint the rad excessive paint around the bung can make them difficult to remove but they are just bits of plastic and will give way long before they can damage any thread

Never even thought of that but yes they probably are, but as all agreed the plastic plugs are just to protect the internal threads and the inside of the rad, not really rocket science to remove

Ive been getting this problem lately with Henrad radiators. I had a word with the company rep and got a special tool for the job.
