Can anyone identify this air valve and tell me the name of it? and also where I could find a replacement? A friend has an old set of struts that use this type of air valve. Even if you could post a schematic so that maybe he can refurbish the valve. They are leaking so the struts are bottoming out. any help will be greatly appreciated.

Skymaster, I believe.

Valve
 

Looks like Skymaster. Most of the time it is the gasket that fails. I sure John or Anton can get you a replacement. I normally send email and get a response with price and availability. Chinese New Year is fast approaching when everything shuts down

They also twist apart extremely fast when trying to install them. They are very thin brass.
I twisted two apart on one strut within minutes. Don’t use a flathead screwdriver unless it has a V notch in the center to accommodate the air nipple. Otherwise you’ll learn the hard way as I did one day.

Hi

Definitely valve of Skymaster struts.
In the past I have got replacement from Skymaster (takes a while). Also I have seen them in Aliexpress, but can´t seen to find them there any more.
Some models of air guns use the same type of valve, maybe you have some luck searching valves for air guns parts.
