Welding Tips and Tricks

Hi all,

New member with (possibly) a new question. What are these connectors called and what are they most often used for?

They are apparently used by Kemppi, UNIMIG, Bossweld & BOC.

Arm waving doesn't work very well in the shop - the correct name would help.

Thanks
Jack

Actually, they are called "Quick Connects" by a major manufacturer here.

Thanks for that but is that the "department" or the name of that specific connector type? Also, I didn't see this connector pictured in the list but I have to admit that the images were not very good.

I bought some from a BOC store here (Australia) and they were listed on the invoice as:

Part Number: R-40-160910-12-00
Description: QR GAS CONNECTOR

That seems pretty generic. Swagelok, in its "Quick Connects" section, lists several quick connectors but not this one.

Most connectors seem to have a name or are called after their manufacturer (eg Nitto). This one seems to be unnamed - except for a part number - and that only applies at a BOC store.

Quick connect is the name. There are further designations or variations that will be the model number. There different model numbers will designate line size and actual small differences in fitting lengths and connectors. These differences keep you from interconnecting or cross connecting lines. For example you would have 2 different models of quick connects on an oxy acetylene setup. This would keep you from hooking your oxy supply up to the acetylene line.

Thanks. Yes, I realise there are different types and that they are all quick connectors.

I visited several shops, in person and on line, looking for this particular connector. They did not have what I wanted and I could not order one because I didn't have a name for the connector. I returned with a sample and (except for BOC) they did not recognise it and could not find it in a paper catalogue. They could not search on line for it without a name.

This is the only connector I have come across that I have to keep pictures of as I have no other way of identifying it.

So, I learned something new - there are un-named connectors.

Thanks guys.

They use quick connects in medical gas, they only call them quick connects but name the different sizes by gas type. Oxygen is one size, nitrogen another. I spent a month searching the web before I finally found the actual spec drawings for the fittings.

Amazon sells them so they can't be too much of a secret....right?

Thanks Josh. Perhaps this one should be called an argon quick connector. It is used on MIG and TIG (that I know of) so argon and argon mix - and perhaps CO2. Perhaps shielding gas quick connector would be better.

At least I know where to get them now.

Thanks again.

Strange, I've always called them "quick disconnects". Guess it just depends on which side of the operation you want done quickly

They are not a secret, just nameless.

Those look like the Chinese version available on Wish and others.

Good point - and even quicker if you don't turn the gas off first!

I use the same name. I use those for coolant as well. Work great.
