I just completed my first regulator service. My SP MK5 now has all new O-rings and a HP seat. I pressurized it hooked up to my IP gauge and then closed the tank valve and left if overnight. IP is a steady 140 PSI!!
Thanks to all of you that provided advice and assistance.
I'm amazed how simple the MK5 really is, but I can't image how you'd go about machining one out of a block of brass.
