Expromizer V4 o-rings

[Viper_SA]

Hi all,

So today I had to replace all the o-rings on my Expromizer V4 to sort out an issue with air breaking the seal. Tank is now 100% fine, but I'm stressing out that I don't have spares any longer. I've never used any of my other tanks' spare o-rings. Does anyone know if these sets are available separately and where I can buy a set?

Thanks
