Evening peeps,

Which compound would you go for ? Boss white ? Plumb centres jet blue or fernox ? Whats the difference between blue fernox tin and yellow ?

Cheers

Jet blue v2

Does Loctite 55 come into this - I couldn't believe how good it is when I first used it...

Incredibly strong, have you ever tried to 'snap' it like you can PTFE tape?? Cut's your fingers off first.

The laco one is good but expensive.

Jet blue and loctite 55

 

[Jim Goodenough]

What about Rocol Gasseal.... it's sticky

You could tow a car with it lol

I like Rocol Gas Seal for gas applications.

The same one that I answered the first, second, third, fourth time etc......... the same question was asked.

Could be worth using the search function on the forum give you an idea when loads of people used to be on here.

Not Boss White, except on heating male/female taped threads.
It will seal well, but it hardens (including in the tub) and it ain't potable.
As above, do a search as loads of old posts were done in old forum

Thought it was just me. Used to get half way through tub of BW, then it went hard. Gave up on it. Fernox seems better.

Lyn seed oil

Yes, does wonders for your cricket bat.

Yes, I still have some linseed oil.
It revitalises ordinary Boss White, as I think it is an ingredient of it.
But I really am fed up with Boss White hardening since it started to come in the plastic tubs, rather than the metal tins, which might explain why the Fernox paste from metal tins is better.

Do you mix it from new as mine normally sits on the shelf for 6 months and it's fine all the way through

Long time since I ever put linseed oil into Boss White, Shaun.
Tbh, I don't need Boss White much now because I use V2 paste nowadays on compression and male and female joints and only need Boss White for some situations. So it tends to lie unused for long periods.
Every tub I buy has a hardened skin on top of it

Yea peal the skin off and give it a good mix good as new

Still gets a crazed and hard skin eventually, - a bit like the top of a creme brulee.
Guess I can't expect it to last months in good condition.
That is one reason I prefer the non hardening V2 stuff. But Boss White is superb for sealing threaded joints on heating systems

 

[Jim Goodenough]

Many years ago, we had a weep on a threaded barrel joint and one of the plumbers working with me got a piece of slate and tapped it into the screwed fitting and that sorted it... I was impressed, I think he learnt it from his dad.

 

[BILLENK]

Jet lube V2 plus as well, good as gold.

And loctite 55 for threaded

 

[plumbandplumber]

Anyone used this stuff? Looks like you can just spread it on a thread and do up the joint. No hemp or PTFE.
