Hatsan Hatsan Fitting Threads

[OneAcreFarmer]

Does anyone know what style/type of threads Hatsan uses on there airguns?

can you be more specific as to what part of the gun and gun model, as to generalize most threads are Metric but some maybe BSPP or NPT.

The gun in question is the hatsan Velox and I was wondering what thread the nipple is where the air tank fastens. The jet also has the same fitting

The gauge on my Vectis has M10X1 tread.
I think that the gauge and fillport on the Velox are the same.
