Hi Aggy Kev doesn`t live very far from us. Make an appointment and nip through. You will be amazed how fast he works his magic. Might save some frustration in the long run. ATB Ken.

Just got the reg to sit at 1500 psi but not happy with it,
The washers are (()) But the nut is not contacting the washers the beliville washers gan be rotated when assembled but it Tighten it to just touch them the pressure jumps , also when the bottle is unscrewed the block leaks back through the bottle adapter.

It's all back and working consistently on the chrono just under powered ,
Not a big fan of the reg at all ,only played with the fx ones and they aren't as we made but work much better across a larger range
