which quick connects?

[ch1ch2]

I basically see 4 type quick connects.
Flush Face, Agricultural, 600, 700 series.
How do I know which ones to buy?
Which ones interchange, if any?

I guess it depends on what you need them for. Most skid steers use flat face. My tractors use Ag type with ball like these.

Not sure if any interchange

Mine have the flat point on them so they are the 600 or 700. They are on my NH and IH.

Here's the 600 / 700 fittings. I've seen them at local tractor stores also.

I take it none interchange.
So when I look at the female end how do I know if it is Series A or Series B?

Not using that type connector. From the diagram it appears they are not interchangeable. Sorry I can't help.
Hopefully another member with a NH or IH will reply with your answer. If not, try re-posting in the NH section of this forum.

When it comes to Quick Disconnects - some brands will interchange with some others but they need to have the same profile. You can see what I mean on this page.

If you are replacing a current quick disconnect, you'll need one the the same profile. If you are replacing a pair - male/female - you just need to match the other end - commonly NPT.

If you are building or adding a quick disconnect then you can purchase whatever you prefer as long as they will attach to the hose - again usually these are NPT ends.

Most ISO 5675 "AG" type will interchange, some have "balls" and some have "poppets" and technically will interchange with each other, but in general its not recommended.

If there is a specific fitting on your machine your trying the match, post any numbers off of it and I'll cross reference it for you. We also have a chart on the website showing the common "verified" fittings that we know about.
