At the time, with shipping, it wasn't that much different in cost to order the complete compressor cylinder assembly from AliExpress, so I did that.
I have a spare and some other parts in case mine, or an acquaintence has a failure.
My Nuoge is a backup for my GC CS3 which I use at the range to fill my PCPs. I give the Nuoge some excercise from time to time.
One day per week at the range, typically 6-7 hours, with 80 mile round trip means that I don't want to be stuck for lack of air.
Is there more information that I might be able to provide?
