Plastic Hydraulic Quick Disconnect

[WillAtCahaba]

I'm looking for this coupler. They come on some of the hydraulic hoses for Kubota construction equipment. Usually going into the pump. I've attached an image below. Has anyone ever seen these? I'd like to buy them without the hose. It's 040 in the diagram

What does the male end (mating) look like? From picture they are pilot lines to an HST pump so presumably less than 500 PSI.

Do you need plastic or would steel or brass be acceptable?

I haven't actually ever seen the male end it goes on before. This is all I have to go off of. I guess it doesn't really matter if it's plastic or some form of metal. So long it worked.

I have never seen such plastic quick coupling. Last year, My boss said we would start developing a plastic quick connector , but a whole year has passed and there is no progress. If it is metal, we have many kinds of quick couplings.

BMW used plastic quick disconnects on the fuel lines on some of the motorcycles 20 years ago. These were prone to fatigue failure after running for a period of time. Companies made metal replacements. I don’t recall the company name though.
