Feinwerkbau genuine replacement seal
# 3.4.000.206*
This valve seal is inside the air regulator. 

*Please note that is you need to change this seal it is HIGHLY recommended to have a Feinwerkbau technician to have your regulator reset to the correct air pressure after repair. The regulator need a specific ''BAR pressure '' set in order to have the best performance as set at the factory.
Failure to do this, performance may be erratic. 

I do have the appropriate tools and pressure gauge. (Tools are not for sale)
