regulator help?

[lschiavo]

SJust trying to set up a dual regulator my fil gave me. One side is leaking from the hole in the ring that the adjustment screw threads into. I took both sides apart and both diaphragms / gaskets have a hole in the center where they push against the adjustment pin. I have never had one apart before so am not sure what is normal. Do I need to replace these gaskets?
Thanks for any help.

Edit. These are REGO.

Anyone have any advice on this. I have been searching with no luck. Thanks
