Where do I get replacement tube hardware

[deshet]

I am new to these tubes and don't know much about them.
I also don't want to overspend or buy oem if I don't it.
I have wing tubes
I need the pressure relief valves and fill valves.
I am not even sure if I have the names of things right or the parts and sizes are generic across the board.
Thanks

My tubes are made by Wing for the US Navy

One of my boats has all of the fill Valves and pressure relief valves and the other doesn't have any.

Are these universal?

The valves are not all interchangeable and neither are the pressure reliefs. Also the pressure reliefs are available in multiple blow off pressures. Many wing tubes have Mirada pressure relief valves and Halley Roberts inflation valves.

Can you post a photo showing what exactly is there? Might Help to identify what you need.

Here are some pictures of my fill hardware.
The only name that I can make out is Halkey Roberts

This the hardware from the newer hull.
