Harder & steenback ultra



Hey guys just purchased the ultra harder and steenback airbrush. I know this is the bottom of the range for harder and steenback. Wanna use it for canvas work and miniature modelling cause I like the size of the needle 0.2. Wanna know if they use a Teflon seal. I know they use a o ring called Viton but I know nothing about it. Wanna run some bad stuff throw it wanna know if it can handle it. Honestly thought for the price I paid it would be a standard feature
The schematics I have says both the nozzle and bearing seals are teflon. The seal in the airvalve is not though.
