These guys do. I believe it's 2mm ID x 1mm thick you need for the centre pin bushing fitting?
OR2X1 Metric O Ring Nitrile - ID: 2mm & Thickness 1mm
OR2X1 Metric O Ring Nitrile - ID: 2mm & Thickness 1mm
Its the AFSV3 that could be used on a GGTB!
I bought both from a user on ECF. OMG I just opened the package and they are both in 100% shape. I couldn't even imagine it would of been this nice and WOW is it smaller than I thought. Will take a picture soon.
