Another fitting question about fittings


#1

Sorry, I know…

My Cat pump came with a female QC on the high pressure side. It seems to measure 5/8" but can’t get a bead on this.

I need a male fitting in case I rent a surface cleaner with a female connector.


#2

I think its m22


#3

It should be a 3/8 QC. Post a picture?


#4


#5

I’d take a pic with the fitting off but it’s pouring out.

If it helps any, the fitting is marked ‘OEM’


#6

I agree on the 5/8, i was thinking different manifold until i found your pump pic.


#7

Does this help any? Has 7100019 on it as well.


#8

It’s 3/8… it’s very common. You can buy from pressuretek, or amazon or local hydraulic hose repair shop, or local pressure wash supply store.

I’d go through there and buy different variations of 3/8 and 1/4. You’ll always need them


#9

Ok thanks, I need to find a local PW supply.


#10

If you need it in a pinch (tomorrow) you can pay 400% markup at some hardware stores… ACE usually carries the Apache brand


#11

No kidding, ACE Hardware has fittings? I was just there to pick up some oxalic.


#12

Shux, i didn’t think it was that small.


#13

Home Depot has 'em but I’ve forgotten if they were stainless steel. If you can you want SS.


#14

Makes sense now, it’s the inner diameter that is 3/8".


#15

Errmm, sort of. Do a little reading on “nominal” pipe measurements. Once upon a time, pipes’ inner diameters matched their labeled sizes. Since then, wall thickness got thinner, and it’s the outer diameter that became standard.
