Schnellkupplung 1/8" mit Ventil

I found this to be an efficient way to regulate my airflow, however I can tell it leaks on occasion which was not exspected by me for specifically buying this brand. Though I still rate it a 4 as the problem is easily addressed by turning the nob either back or forward a little when it happens.

Finding air tight couplings for airbrushing can sometimes be difficult. This Harder & Steenbeck quick connect coupling with small regulator valve is perfect. Best one I have found.

Nice unit ... used to replace the Grex version which is much bigger. The H&S is lighter and less intrusive ... It is also less likely to be accidentally adjusted by rubbing the palm during use. Wish I'd known about these sooner !

Excellent Harder and Steenbeck quality. Works great with all my airbrushes using 1/8 QDs.

Small and unobtrusive; no leaks; does what it says it does
