FX FX Crown regulator problem

Lamar,
Putting on the o-ring that broke off can be a PIA. It is a 2x1 NBR90 o-ring. The NBR 90 means that it is very stiff and hard (relative to the other ones - NBR 70). That is why Jeff and Jack of Sub12Airgunners made the "witches' hat" that B&K sell. In the video I sent they show how to use it.

I am pretty sure the broken o-ring was the source of your problems. I would not try to replace the o-ring in the rifle body unless when you re-gas the rifle you are getting a bunch of air out of the regulator "breather hole" in the right side of the action. If you decide to repace that o-ring I would get a pair of jeweler's glasses with a light (cheap on Amazon) so you can see what you are doing. Then follow the advice in Post #10 and the Sub12Airgunners video. I have replaced these things at least once in all six of the FX rifles I have owned. Tedious, but doable when you can see it.

Cheers,
Greg
 
Yesterday I contacted Utah Air guns and ordered a new OEM regulator with the newer brass piston. The cost was only $46.44. Don't know if the O ring in the body is included. If not, I'll just go with what's included with the regulator. I think all the regulator O rings will come installed. Looking at that witches hat photo, I think I could easily make one from the removable tip on a cheap mechanical lead pencil I have.

The price is the same as in Spain, the regulator seals come all installed, in an attached support (a screw) you get the Bella-Ville washers, it also comes with a bag with some lubricant, it also contains the O-ring that is installed in the body, that is, the kit is plug and play.
