Diana Diana Airbug/Chaser O-Rings?

[CBKidd]

Does anyone know the correct sizes, durometer, and material used for the barrel/receiver junction? Those two on the barrel tenon are REALLY thinly (like maybe .035" CS) and hard to source locally. I thought I could just run down to the local True Value and pick some up. I think those two thin ones (on the tenon) might just be Buna-N material, so at least the material is common. However, the breech o-ring is brown in color, which normally indicates Viton material. Anyway, does anyone know the correct info on these? Just looking to lay in some spares is all.

the 2 barrel to breech are .8mm x 8.4mm buna 70 will work 1mm will not work
the barrel end Orings are different sizes from .177 to .22 but can just buna 70
.177 are 1.42mm x 4.7mm
.22 are 1.5mm x 5.50mm
yes the chasing of Orings been there done that
also the bolt handle take a 2mm x 7mm to fill the grooves
the transfer port is 2mm x 6mm
all sizes are cross section and ID
check the Oring Store
