Sealing Brass fittings

Post  Gomer on Thu 14 Mar 2019, 3:52 pm

Hi all,

Whats the best stuff to use to seal the brass elbows into the boiler and the copper pipe to the steam head. Steam seal or PTFE tape?

Thanks in advance.

Regards,

Neville

Hi Gomer or Neville

Personally I use tape on everything. Never had a problem with leaks or removal if needed.

i used a small amount of tape on the threads and a smear of steam seal. they are never likely to ever need to come out in a hurry and wont leak.

Small amount of tape, dont go mad, I see folks far to often winding piles of tape round fittings and it just should not be needed and can actually damage the threads and get in places it shouldnt.
Learnt my lesson when my injector died and when stripped down I found a tiny bit of PTFE tape stuck in the cone Rolling Eyes

Thanks for the advice everyone. Never quite sure on what sealer to use and where with steam and like most only enjoy doing the job once!

Many thanks,

Neville

A small amount of PTFE tape is good for permanent fittings. Do not overdo it as it will damage the fine brass threads. It only takes a few turns of tape to achieve a good seal. For threads that are likely to be removed frequently, such as the boiler washout and inspection plugs, I use Loctite 567 thread sealer. Not cheap but no danger of thread damage.
It never ceases to amaze me just how much tape/sealer people use on thread sealing in the belief that the more merrier, just not so. I had an unfortunate laps of brain at one steam outing and forgot some of my traveling tools and service gear and had to filch some PTFE tape to seal my smokebox inspection plug, after filling the boiler, and only had enough for two turns of tape on the plug.
Absolutely no leaks whatsoever.  Smile  Smile  Smile

A different option on wash out plugs and fusible plug etc is a light smear of copper slip grease on the threads, they spin out with ease every time and no leaks what so ever on the agri and boiler inspector always happy Cool
