“hsnmz”What could cause the regulator to creep and how to correct it.


As Kris has said, the pressure will cause the piston to “embed” in the seat, this causes the pressure to increase. The way to fix it is to replace the sealing seat.
I experienced this “creep” with a gun I put a bottle on whit a ninja regulator. First shot was always faster. I took the reg apart and sure enough the seat was “embedded”. With the Ninja the “seat” is actually a “ball”. I pushed the “ball” out, rotated it around, and pushed it back in. All shots the same speed now.
