Hi all, a small question that i would be pleased if was cleared up-are brass couplings multi flow directional? Or do they flow more solution say male to female etc? Just something thats stuck in my head and im sure i will get the answer on here. Many thanks in advance. ???

yes water can flow either way through quick connects, when there connected plungers are opened allowing flow any direction.
-
Does anybody know where they can be bought in stainless steel?
-
You should be able to get there from anywhere you get the brass ones from. They are more expensive
but are superior. The male ones are easier to find as the female ones are hideously expensive because
of the making of them. If you have difficulty finding them they are far more common in the states so
trythere, best, Dave.

Local suppilers charges
females approx £7.50
males £3.90
that was price last month
is that a good price
did get a stainless steel one once cost me £25 for a female and was'nt worth it as it wore out the brass one faster.
-
That is a good price, imho.
I bought a female quick connect and a thread adapter t'other day and paid £16 all in.

Hey Paul. I have found the same so if you are using stainless you should use it for both male and female. Other than that its not like they break down that quick to make any difference. Best, Dave.
-
Dave,
Youre exactly correct stainless is much harder than brass and if you mix them any grit or poo will wear out the brass PDQ, wheras not affecting the stainless. The prices quoted above for male and females in S/S are very good .

Thats great , but who sells them ?

That would mean buying two ( steady on i need a sit down!) my wallet's having a panic attack.
It's not that a can't afford too, just i'm too tight!

Hi,
The brass couplings are no good for high pressure and crack.
The stainless one are too expensive.
The best ones are heat treated steel. They don't wear, crack and are plated to prevent rusting.
All are available from RS Components online under quick action couplings.

really!!!!!!!!!!!!!!!!!! run at 3000psi daily to wash the van and never had one crack what type are you using
-
Paul,
The brass couplings are designed only to work at 180 bar, with a max temp of 90 C the nickel plated steel are for high pressue and work at 280 bar 110 c. The brass are more expensive than the steel ones.
Are you sure they are brass. The nickel plated steel can also look like brass
-
maybe?
personal i alway look to make sure the female has double o rings as the single type don't last long.
how can i tell the difference between brass and plated steel? i'll have a look tommorow
-
Hi,
I forgot to add yesterday I also used RS Components for all my pushfit and quick fit couplers in my previous job ( where I used pneumatics), and we were ordering hundreds monthly. They are made by Norgren and SMC and you can also get them from these people direct.
All these company's are huge and not really the places to order one's and two's of stuff without an account. Speak to olympic cleaning supplies or order them through you're local plumbers merchants. The nickel coated mild steel look like stainless but you'll know the difference by the price.
Regards,
Adam.

Catman, sorry mate but you are talking cobblers. Havent had a crack in 13 years at 3000 psi and or higher in brass or stainless. Stainless cost more than brass and nickel plate doesnt look like brass. Apart from that you are spot on. Best, Dave. Oh and brass and stainless by nature dont rust anyway.
-
Paul, they are different in colour. Please note I have nothing against nickel plated q/d's just that the comments made about them and the other q/d's were very inaccurate, best, Dave.
-
If you go to the manfacturer of the couplings and tell him that you are running 3000psi on series 60 brass coupling then they will tell you that they are wrong.
The steel coupling are for this pressure, they are zinc plated with chromate on top to give a yellow appearance. To the layman in the street, might say they look like brass which they are not.
I have run brass coupling off my ninja on a trckmount, overtime with the outside temp, and quick expansion with hot water they cracked.
From a cost point, the steel couplings are cheaper and run at a far greater temp. Since changing all coupling s to steel I have had no problems.

A magnet will stick to plated steel but not brass.
A magnet may or may not stick to stainless steel, depending on what grade of SS it is.
