Plumbers Jointing Paste ???

[Mike PalingParticipant @mikepaling69128]

Hi …

At some point in the future I will need to assemble various threaded copper pipes on my Tich boiler both internally and externally.

These will obviously need to be steam tight … but knowing me I may well need to take things apart again at some point !

 

The “Tich” book keeps on talking about “Plumbers Jointing paste” …. I do not know where I might be able to get something sounding like this … I am sure that grabbing a big tub of this sort of "stuff" from B&Q or Screwfix is not the best option!

Can you suggest which jointing compound that you show in your catalogue would fit the bill for me???

 

Cheers Mike

Boss white is what you want, its sort of very soft putty, even after a lengthy period is will still be soft and its easy to disassemble, clean up and reassemble.

Available at most plumbers merchants and a small tin cost coppers !

I used to be a Boss White fan, but have now moved over to Tru Blu pie thread sealant – excellent stuff in my opinion.

I find this LINK excellent – nice and sticky!

Hawk White does the same job as Boss White.

Boss white and most of the similar products are only rated for low pressure steam (up to 7 bar or 100psi) and temps around the 200 deg c mark.

I've been using Rocol steam seal for many years in higher temp/pressure applications, this is rated at 193 bar (2800psi) and has a temp range up to 600 deg c

Loctite also sell pipe sealant for high temperature applications.

Boss White and Hemp was all town plumbers had to make a seal on water pipes before P.T.F.E came along. I've just renewed some cast iron down spouts on a period house and used Boss White and Hemp on all the joints – stays just movable enough for expansion. The Hemp used to be unpicked rope known as Oakum also used mainly in caulking ships timbers. Prisoners and Workhouse inmates 'Picked Oakum' resulting in bleeding fingers as part of their sentence.

Many thanks for all of you taking time to send me suggestions.

I am keen to get the best sealant that will be steam pressure tight, cope with high temps and also be capable of of being taken apart without too much trouble should I need to. Here I am particularly thinking of the pipe connections in and around the regulator which is buried internally inside the main flue of the boiler.

The three suggestions that "might" fit the bill seems to be the following …

(1) Tru Blu thread sealant

(2) Virgin White Multi Thread Sealant

(3) Rocol Steam Seal

I am prepared to buy all 3 and do some tests …. but … to save some hard earned cash can anybody suggest which one of these going to "fit the bill" best ???

I have tried to search for the tech specs for each of them but I can't make up my mind.

Cheers Mike
