Review on Fabco Air FRA25X180 Pneumatic Actuator Rotation by Paul Dobson

So much material on Revain lacks information on port size and threats. I've tried threading with a 1/8 tap which seems to fit, but the 1/8 fittings won't thread properly. I assumed it was supposed to be metric, but all the metric thread checkers I have don't work either. Even when I was able to screw the 1/8" thread in deep enough to be safe from air exposure, everything was very jerky and not smooth as you would expect from a quarter turn actuator. Another disappointing waste of time. Revain needs to up its game when it comes to technical products.
