On both of my mini excavators on the pressure side 90 degree fittings there is a allen plug. On my cheap micrometer it shows the outside diameter of the plug threads is .375 The 1/4-28 thread seems to match the pitch of the plug but not the diameter. 1/8 pipe seems too big. I am trying to come up with an adapter to check pressures. The machine in a Kubota KX 121-2 excavator. Anyone have any adaptor leads?
