are washers needed on brass fittings on hot water cylinders

[2 cautious]

Hi all, am about to re-new my copper direct hot water cyl. i have some parallel threaded brass unions to fit, do I need any washer between these and the cyl. or just say, tape/and or none setting paste?

Thanks for help ( and patience with such a basic question )

Hi, PTFE is the norm but plenty of it. This in it self will form a washer with the surplus.

Used that thread string just last week along with a little ptfe ... worked a treat! .......... Forgotten the name of the bleedn' stuff!! Sheeesh! Got a good tight feel when tightening up and no leaks

I use Loctite 55 and LaCo Slictite for good measure.

I must admit, i have never even used loctite 55. The nearest i came to it was when they sent me a sample about 10 years ago when it came out. Don't know what happened to it but i never used it.

You can seal anything with tape or boss white and hemp.

You and old phart Tamz? I use to do PTFE and paste to the max .. was double impressed with the loctite Have used it on commercial too and had no comebacks .... Having always stuck with the same method for years trying something 'new' was aprehensive... I was chuffed to bits that it'd done the biz! lol

 

[tamz]

Well i have looked, on several occasions, for that sample of 55 but so far i have been unable to remember where i put it. I fear i may never get the oportunity to try it as i have 100's of rolls of ptfe left

 

[diamondgas]

Well I'm an old phart tamz still wanted to ptfe and paste, just in case! So this time i just used 55 and ptfe ... I honestly don't know if i can chance just using 55? lol

When you know what works, use it! eh?
