Regulator - 5/8ths 3k(psi)
Pull pub-quality pints from a full-size CO2 tank with steady, foam-free pressure. This single-tank regulator is built for serious draft setups — homebrewers running multi-keg kegerators, mobile draft trailers, or anyone scaling up from disposable cartridges to a refillable 5 lb or 10 lb CO2 tank.
Why this regulator
- Built for refillable tanks: Standard 5/8" CGA-320 inlet thread connects directly to most US-spec aluminum and steel CO2 tanks.
- Dialed-in low-pressure control: Tuned for the 5–15 PSI working range that draft beer, cold brew, and carbonated cocktails actually need.
- Long-haul durability: Brass body and diaphragm rated for 3,000 PSI inlet — the same hardware pros use behind the bar.

How to Install
- Confirm the tank valve is fully closed.
- Hand-thread the regulator onto the CGA-320 fitting; finish with a wrench (do not over-torque — the seal is in the nylon washer).
- Open the tank valve slowly and check the gauge.
- Adjust the output knob until you hit your target serving pressure (5–9 PSI for most beer styles).
Frequently Asked Questions
Will this fit a paintball CO2 tank?
Yes — paintball tanks use the same CGA-320 thread.
What PSI should I run for beer?
Most ales and lagers serve cleanly between 5–9 PSI at refrigerator temperature. Stouts and nitro pours run differently — see our Nitrogen Mini Keg System for those.
Can I use this with a mini keg cartridge?
No — this regulator is for full-size refillable tanks. For 16g and 74g threaded cartridges, use the regulator that comes with our Premium Draft Mini Keg System.
