I have fitted a new radiator and tried 3 times to seal it fully. I have trimmed and cleaned the pipes so that the olives on the valves fit and seal, that did not work. I have also PTFE taped the thing to death (yes I have wrapped it the correct way) and that has not helped.

I dont want to drain and redo it all again, I dont have the time with a new baby ready to drop.

Dare I say it, I want a quick and simple fix. It is such a small leak that I am sure there is a product that I can just wipe round and will seal it.

A quick google didnt bring anything up.

Suggestions?

liquid ptfe and don't over tighten the nut

Bit gash but wrap the olives In ptfe tape and nip it all up. Has worked for me in the past for a seemingly incurable leak.

I'm going to let you into a plumbers secret.... leave it alone.

Any small drip will eventually crust up with limescale and other sediment, and then stay like that for ever more. You will go insane if you try and fix every drip, it's really not worth it. If you're worried, put a small pot or similar to catch the drips, then let it seal itself.

(By the way, I'm not the plumber, it was a plumber who told me about it)

How about a little smear of Evo-stik 'plumbers mait' (not misspelt) around the olive?

Unfortunatly the only way is to drain it off and remake. check theres no damage to the pipe/fitting, some ptfe tape on and just pinch up should be enough

Fernox lsx sealer.

The leak may be from the thread of the valve and not the olive. Try refitting valve with fresh ptfe and a smear of jointing paste.
This is the most common problem usually on ladder towel rails.

Make sure its not coming from the gland seal on the valve, take the knob off, you'll see a nut, give that an eighth to quarter turn clockwise to tighten the seal.

Thanks for the ideas I am hoping for it to seal its self. That would be nice.

I fear I may of overtightened the nuts as in anger I went to town on them last night!

I dont want to dismantle and redo it as I have done that twice already. I would like a smear on sealent really.

I covered the olives in vaseline as well as the pipe. Its leaking from there still and the actual radiator outlets.

Ill leave it for now. The weeks are flying by so ill blink and it will have sealed itself!!

Prob a bit over the top but it's a cool advert

Loctite 55 is good stuff for the leak on the towel outlet. Dont use a leak sealer that you pour into the system if its a newish boiler,as some manufacturers dont approve it.

In the olden days there was a product called Boss White which always worked brilliantly. Then came ptfe tape which also works brilliantly except when it doesn't.

I've used Hermetite in the past to seal small drips.

The hard/corrosive water around here will seal small leaks after a while, I've had quite a few weeps, they have all sealed themselves. Disassembly usually involves a hacksaw (e.g replacing a corroded ball valve), whether it's 'leak sealed' or sealed 'properly' so there are no negatives. As long as the fitting is secure on the pipe, I'd leave alone for a while.
