fill valve help

[Spartan09]

as the title suggests, i have some questions regarding fill valves on some of my kit.

i have the following leaking gear:
- 3 x Vorsk hicapa mags that are leaking from the fill valves, one also leaking through the outlet valve,
- 1 x original magazine for the EMG John Wick Hicapa
- 5x MAG POM CO2 moscarts (3 leaking from oring on the threads, 2 from the valve inner o ring)

when looking for replacement fill valves and o-ring kits, i see numerous different options and i dont want to buy the wrong parts.

so my question is, does anyone know what type of valves i need to buy (TM/WE/AGM etc) , and for the MOSCARTS, is there a specific material O ring i need to buy for CO2?

With the pistol magazines it might be a matter of finding a flat screw headed screw driver and tighten the valve first. If that does not work you might need to remove the valves and magazine plate and check the seals.  If the seals look worn, just take them to a hardware store and get them replaced.  
 

With the Moscarts, replace the seals and also give everything a good clean.

Thanks sneaky. 

Have given the moscarts a clean and replaced o rings on the valves, hopefully that fixes the issue there. But they are just normal o rings i got from work, designed for engine work..  not sure if they can cope with CO2 though.

I tried tightening the pistol valves, with no effect. The outer seals look good, but they seem to be leaking from the centre of the valve itself.  Have tried cleaning and lubing the valve as best i can, but aside from 1, they are all still leaking.

Definately think i need to replace the valves, but i need to know what type of valve they use before i order them. This website lists different valves for TM, ASG, APS, WE etc...  but i dont know which ones i need to work with my mags.
