Just bought the new Prochem upholstery tool last week.
Friday afternoon was first chance to use it.
Really looking forward to trying it out.
Showed the old couple whose suite it was what I would be doing with my NEW addition even showed them the tool.
Right all set up let's attach the tool to the feed line         oh   errrrrrrrrrrrr     it's got a female coupling on it not a male.
Back to the old tool.

it should have a female coupling, it works out cheaper in the long run to have the male on the solution line and all tools as females.

plus dragging the solution lie across the concrete will be less harmful to a male QC

My experiences are  different Mike:

"plus dragging the solution lie across the concrete will be less harmful to a male QC "

If you drag a male QC across a concrete floor, the contact edges of the fitting becomes chipped and burred. This leads to a poor fit, damged "rubber" seals in the female QC and water leaks.  Plus, your hose will always have a male one end and a female the other, so it shouldn't make any difference anyhow.

My practice has always been to roll up the solution hose starting at the male end. This way, it's only the external release collar of the female that gets dragged across the ground which doesn't affect the integrity of the join or seal when in use.

As for the tool end fitting, by having a male on the fitting, it's cost is cheaper than having a female.

However, following the hose through from tool to machine, a female on the tool will mean a male on the hose and pro rata all the way back to the machine. This way, if you pull or drag on the hose when in use, the movement can't "undo" the QC's by snagging on the release collar.

If anyone can unravel all of the above, well done

Safe and happy cleaning

That's all well and good but the machine has a female coupling so all attachments have to be male.
Think that's the right way too.
Thinks most pumping systems run male to female.
Just thought it was a cautionary tale, always check before you leave the shop.
Been back today and to sort it and noticed the one on display still has a female coupling.

Ken sorry mis-typed I meant to say 'female'  and my comment about dragging them across the concrete was a bit tongue in cheek, 

if you have one solution line with a male QC  & 6 tools with female QC during a number of years all these QC will wear out and need replacing

So...... you will have to replace 1xmale QC &  6xfemales QCs this will cost double the price of the exact opposite number Of 6xMales & 1 x female.

its cheaper the way I suggest

John change your QC on the machine, they can be used anyway round

[Ken Wainwright]

To be honest Mike, because I lube my QC's at least once a week, replacement is so rare that it has novelty value

Safe and happy cleaning

Cheers for that Mike everything hunky dory now.
What you recommend as a lube     WD40 or similiar??

John

[Ken Wainwright]

WD40 can damage some seals. So can vaseline. I use a silicon spray. I once had a sample of a Parker brand silicone grease. It was the Dogs best Bits. Expensive, but sooooooo economical and longer lasting than a spray.

Safe and happy lubing
