Wika Gauged Royale and Crown

Nutcracker, I'm pretty sure the factory plastic washer/bushing is tapered on the bottom side to fit a tapered hole in the receiver. Without the washer I don't think the O-ring can seal against the tapered hole but instead it just squishes down in it without consistency. I think that by using the washer and the chubby O-ring, the O-ring seals against the surface of the washer plus it expands and seals into the threads as well. Just my take..

That makes sense. Will try that when I get the Wika. Thanx.....

Very interesting, I will link this to long brown box. He had a gauge fail on one of his Royals. Good work on that.

I have ordered 6 of each type, WIKA & HUMA, timing the gauge properly would make everything much easier!

JKing, Received the Wika Gauge yesterday. Used fat o-ring on top of flat disc like you said. Indexed perfectly. Here is picture today after filling to 220 bar yesterday. So looks like that is the ticket. I swapped dust covers with my older Wildcat as it has the removeable inner piece. The Wika fits w/o removing the inner ring. Guess I could take it out. Better than removing material off dust cover or gauge. I doubt you can get those old style dust covers anymore, but maybe.
