Is there a leak sealing fluid for thermal solar?

[Sharp Point]

As title guys n gals, been to a job today and customer asked me to look at some weeping compression fittings. Will fernox f4 be suitable?

thanks

Personally i hate any leak sealers , but surely when you can see the leaks its easier to fix them. If you do check they are brass olives and not soft copper

Does all solar leak? seen 2 installs and they both had seeps at the compression fittings...

I didnt think you had solar up there ian, i didnt think you saw much sun

Cheers TFJ, looking at the weeping joints i can see in the garage, remaking them could be possible......but i'm assuming there will be more on the flow/ return pipes behind the insulation and plasterboard in dormer roofwork to the panels on the roof.

Lol i thought you meant one or two ,sounds like them all.

There's dried residue all over the pump station and about 6 x comp fittings, so if thats a little snap shot of the overall system, i assume theyll be more!! And as IDCHAPPY mentioned it's not the first time i've seen them on thermal solar systems filled with glycol.

As said , copper olives maybe

We do mate, sun falls on 1 Tuesday a month

The problem is the massive expansion and contraction changes from 150°C down to -4°C can happen in one day - think clear skies, bright sunny winters day, freezing cold nights...

If the joint isn't done 100% correctly, with the right materials, then you'll find weeping joints.

Maybe all these solar fitters nned to start using these? Seems as if every thread on solar I read on here has a leak problem?

My missus has just informed me that sealing against oil is best achieved with an anaerobic sealant. So if you chaps/gals who install solar are dealing with oil? then Loctite is not an option. Sorry

they are chatting about solar systems filled with water/glycol, no oil involved village

Look in our tools tray and you'll find Loctite 55 and 577, not a mm of PTFE to be seen. Can't remeber the name of the sealant we use on the solar thermal, though it is a special V high temperature one, could be the Solar-Fermit one, will have to check when the guys are back at work tomorrow (I gave them a day off )
