So I had my SFT at the field. Used a friend's bad tank apparently and it blew the c clip and mesh screen out of the fitting. No issues there as I'll just replace the macro fitting. Here is the problem. I can not get this thing to unscrew from the regulator. Are there any tricks to getting this off. it's not the typical swivel 90' fitting. Its a non swivel with no place for a wrench like most. Having trouble uploading a picture but I've copied a link of the pic for you to click on. Thanks for any help.
