Where to buy quick connect connectors

I am in a bit of a bind, I just bought a new cylinder and it has quick connect connector on it, my old cylinder is a cheapy one it just takes a straight vacuum line. Is this something I can pick up at autozone/orielly’s? Or do I have to get it on the net.

You’re from the US so this is your safest bet:

McMaster-Carr

To be more specific, this one works for fittings used on most commercial cylinders:

McMaster-Carr

Sigh, be gone from home about 3 weeks starting tomorrow, I was hoping to try out the pump tonite.

I am looking to get a few of these and the only place I have found is Le Luv that ships internationally. Works out pretty expensive for a cheap item.

Cannot find them on aliexpress or ebay. Does anyone know of a supplier who ships them out of China.

Another option may be to swap to a different type of connector. Anyone tried that?

Just to make sure, you checked with McMaster and they don’t ship internationally?

If they do, these are the PN’s you need:

Quick disconnect male fitting PN: 5012k251

Quick disconnect female fitting shut off valve PN: 5012k29

Tried to make an order but got this email

” Thank you for considering McMaster-Carr for your purchase of couplings, but we have cancelled your order.

Due to the cost of complying with extensive US export regulations, McMaster-Carr accepts international purchases only from our established customers.

I am sorry we cannot help you any further”

I am sure that the quick connect fittings typically used in PE stuff are common world wide. The challenge is locating them and purchasing in small quantities. Suppliers to manufacturing, food/drink, and laboratories are your best bet. Be prepared to spend more in shipping than the cost of the item. I also suggest you buy a few different sizes as there is often confusion in measurements. The o-rings are usually available at hardware and automotive retailers.

Did you checked Alibaba austfred?

Yes Have checked a number of times but the problem might be to find the right description to feed into their search function.

There is a few inside the following link:

Water-proof Efficient And Requisite dvt pump - Alibaba.com

Only one problem. It looks like you have to buy 500 minimum order.

I know LG hanger has them also. I got both ends from them before. And they get it to you fast

Lenny good find. Gprent is right though if like me you do not want commercial quantities

I buy through Aliexpress where you normally can get individual small items. I will keep working through the Alibaba site until I find a description that gets a hit on Aliexpress. You would think some Chinese entrepreneur would offer these in small quantities seeing they seem to be made in China.

I get them direct from here.

The PMC line is what’s typical and the least expensive.

That looks like a very good site, but the main question for austfred: do they ship overseas?
