Discuss Cast iron rad tails affixing in the Plumbing Jobs | The Job-board area at PlumbersForums.net
I made a rig up to pressure test the rads before I attempt installation and the only way I could get a seal was with boss white and hemp. Never tried the the LS-X but using ptfe on its own failed. I do have Loctite 55 but not 577 which I am assuming is similar to LS-X.
Never got around to 55 as the boss white and hemp worked.You had it leak with 55?
Paste?Ptfe and paste. Just done 24 of them.
Paste?
Is there any preferred method of connecting tails to a cast iron rad as opposed to a steel one? Manufacturer says use LSX, never tried this stuff.
Thanks
The LSX will therefore remain unopened. As it took hemp and boss white to get a seal for my test setup will stick with those, at least I know they work.
The jobs done ChrisHello again Bogart,
When I started in the Plumbing Trade `Boss White & Hemp` was the ONLY way to seal `Domestic` / small bore threaded joints.
For larger bore threads there was a `Thread reinforcing string` on a roll which was preferred by `Pipe Fitters` to Hemp for larger bore Pipes / threads.
I think that a Joint `paste` called `Stag` was favoured by Pipe Fitters for both small and large bore threads and I think it was put onto the market in the late 1960`s / early 1970`s [?] - there were only a couple of varieties then but I think that the brand now has a few varieties for various uses.
Now there are many varieties of `Jointing Paste` and liquid sealants.
Good Luck with your Radiator valve joints.
Chris

Thanks for the trip down your memory lane though.
Hello again CHRISX,Hello rpm,
How do You know that Bogart / the OP completed the Radiator connections between Saturday morning and now ?
I have a feeling that You are trying to provoke me into insulting you - however your inane comment displays your attitude / mentality.
I will try not to lower myself by resorting to name calling - unlike yourself when you called me a `Clown` recently.

Thanks, interesting to know. I've seen the sprinkler guys using a string with paste on their threads.
Which was the best method in your opinion?
I was assuming the word string was referring to Loctite 55.
Am about to start the jobs this morning.
Depends on what you mean by bunch up then I guess. Applied in the correct rotation the chosen product is compressed into the thread and any sealant is pushed outwards.Nope correct direction. Maybe I am just putting too much on the thread
Are you serious Shaun, would you be happy to put your name on the ptfe joint?loctite one is spot on
hemp looks to be a bit too much paste but doesnt matter
to clean them up carefully go round the thread as close to the rad as possible and cut the excess off with a hacksaw blade
Well I do know my clockwise from my anticlockwise. A mess? If I exhibited them at the Tate Modern would be worth a fortune.Look I appreciate that you are diy however both are a mess and I'm not convinced that the products used were applied in the correct rotation.

Cheers but don`t need a leason, done 1/8 bsp to 10 or 12" pipe joints over the years, only on the bigger stuff in places like Battersea power station would they be acceptable.yes as thats how boss white and hemp goes
will give you an idea but he doesnt use enough hemp for my liking
