I have a Nitro Duck X Stream which is the size of a pre-set but can be adjusted from 100-900 psi with a special spanner, just a quick twist and there ya go!.
p.s. its for sale with 1.1Kevlar bottle 2 years test left £170 inc p+p
Originally posted by EELZ is it possible to buy a h.p pre-set reg, i.e 800 psi output and re-arrange the spring stack inside to reduce the output pressure to say 450psi.?
it is possible to do this to most presets, but some are sealed. If you haven't bought the preset yet, just buy a 450 psi preset, and you won't have to adjust it then.
