Regulated hose assemblies bring consistent, controlled pressure from your air or nitrogen source to your PCP airgun. Unlike a plain fill line, a regulated assembly steps high tank pressure down to a usable, stable output, so you can top off your gun safely without guesswork. The selection here covers configurations such as a regulated hose with a male Foster quick disconnect on the input, plus heavy-duty regulated nitrogen options built for 6000 PSI service with common CGA580, CGA677, and CGA680 fittings.Choosing the right assembly comes down to your tank fitting, working pressure, and how you prefer to connect. Browse the regulated hose assemblies at TopGun-Airguns to match the setup to your gear.
