FlexiBlok Series Air Line Regulator, 1/4 Inch Ports, 0-125 psi PSI Spring Range, 40 SCFM Flow Rating

For a 1/4 inch line setup, this unit fits right in. The ports are 1/4 inch NPT and it's rated at 40 SCFM, which covers a solid range of shop tools and pneumatic equipment without choking flow. The pressure range runs 0 to 125 psi, so as long as your working pressure falls under that ceiling, you're in good shape. Worth knowing the maximum inlet pressure is 250 psi, so your supply side has plenty of headroom.

This regulator is rated for operating temperatures between 40-120°F, so as long as your shop stays within that range, you should be good to go.

Part of the FlexiBlok modular FRL line, it can be installed as a modular unit in a stack or mounted and used as an individual regulator. It is the 14 Series style with 1/4 inch ports.
