Anyone know what size the o-ring is under the screw/plug on top of the SAR? The Iwata exploded diagrams show the screw in the body, but none refers to the screw or O-ring.
Thanks,
Dave
Take the O ring to the hardware store and match it up to the chart for rubber o rings. I did that with my Micron C plus and the o ring on my compressor pressure release and they were the same. I bought a whole pack for 1/8 the price of a replacement from Iwata.
