Leaking Myson Premier HE Radiator

[Rsian]

Hi, hoping someone can help me out.

Two weeks ago my sister had a radiator fixed which had been leaking. It is a Myson radiator ( don't know the model, but it is smaller than the one in her lounge - see below ). The person who fixed this replaced the bleed vent.

Now her lounge one is leaking aswell, it is a Myson Premier HE radiator. This one is leaking at the top from the opposite side of the one which was leaking a couple of weeks ago ( see above ), from around a large hexagon type nut. I tightened it up and all was fine for a few days, but it has started leaking again. It's only a small leak, but the radiator won't heat up because of it.

Is there some type of seal behind the nut which may need replacing?
I've searched for Myson Premier HE spares but am yet to come up with anything.

Any advice appreciated.

Thanks.

Hi, cheers for that.

Few things.

What valves need turning off?

Will a 'Focus' type shop sell ptfe tape?

Where exactly do I apply the tape?

Cheers.

yes

Where exactly do I apply the tape?

to the threads after you unscrew the hex

The small leak in itself will not stop the rad heating up.

Perhaps the rad has been turned off at both valves to stop the leak and thats why its not heating up now?

It wasn't heating up at all when it was leaking ( it was a tiny leak - one drop every few seconds ). When I tightened it up, about 1/10th turn, the leak stopped and it started heating up again. A few days later the tiny leak starts up again, and the radiator won't heat up!
