Hints, tips & secrets of plumbing - No Banter please!

This is a great tip! Although I'm not sure why you'd need ptfe on cylinder unions.

There is the odd occasion when you can't get the standard cylinder unions on and this could be handy (I used to do it). Most of the time now I use stainless steel cylinders which come with compression fittings already in place.

Must be a regional thing, I've always been taught to use female irons on cylinders and that is what I'm given by the merchants when I ask for the fittings for one.

i have to admit aswell for years i used FI on cylinders, normally got them in fittings packs from the company i was working for. I do use the proper unions now.

 

[Dannypipe]

Got to say, I've use Fi's for years too!

If a comp' fitting would work on the cylinder, I would use that.

I am sure when I compared cylinder coil fittings to Fi's the Fi's were cheaper.

I haven't fitted a vented cylinder for a few years.


I've changed the odd one that's split, and they normally have FI fittings on em if my memory is right.

Well there you go! Apologies for the slight!

Just checked plumbfix prices and 22 x 1"FI is exactly the same price as 22 x 1" cylinder unions.

I find cylinder unions quicker to use as there is no faffing about with tape though. Just a wee smear of jet blue.

Keep a pair of old 15mm and a pair of old Belmont type radiator valves in your van so if you are taking a radiator off without draining the system you can whack them on the radiator when disconnected so you don't drip black water around when you take it outside.
