BADGER R-0023 Needle seal adjuster with PTFE bearing

Because once the needle seal wears out, paint will flow into the rear of the airbrush when back flushing. Because of the threads, it is harder to clean.
Item's price is not bad, but I wish there is cheaper option for international postage.

IMO, Badger makes one of the best airbrushes. Given the chrome is not as beautiful as the IWATA or the H&S, overall, it is a good workhorse, does the job (most important thing right) and parts are so reasonably priced and the service from Ken and his team is unbeatable! A needle seal at this price.... just compare it!
