When using these together with the VG2, does one also need to use a grey silicon insert, as one does inside the cap of a standard VG2 receiver? I had ordered a heap of accessories recently, and wasnt sure whether the grey insert in the mix had any role in this combo. I dont think so, because I cant see how it actually fits.
Also: how far down should one slide the blue cap over the stroker? How does varying the amount of the ribbed section of the cap beyond the end of the stroker affect the performance?
Oh, the gray silicone part is a component of the normal VacuGlide receiver only.When you connect the blue universal vacuum cap to the Autoblow ultra stroker or a fleshlight stroker or other similarly sized stroker, nothing else is needed.
Good question regarding how far it should go. I slide it down as far as possible just because it deforms on high vacuum and just to keep it looking nice, I slide it as far down as it can go, but there’s not any rule about that. Trial and error on this one is your friend. It probably depends on how much air you want to remove/push. It’s different for different size receivers and strokers, and for different preferences.
