Amerex 423 20 lb ABC Stored Pressure Fire Extinguisher (Model 423)
Industrial job sites, chemical processing warehouses, and commercial ship decks demand heavy-duty protection. The Amerex 423 is a high-capacity, stored-pressure 20 lb ABC fire extinguisher designed explicitly to bridge the gap between heavy fire risks and unforgiving weather environments.
Constructed with a heavy-gauge drawn steel cylinder, it is coated in an impact-resistant, high-gloss red polyester powder finish. Unlike residential or light commercial models, it is engineered with a chrome-plated brass valve body and all-metal operational parts to completely prevent oxidation, cracking, and pressure failure. Filled with siliconized monoammonium phosphate, the dry chemical agent rapidly coats combustible materials, smothers flammable liquid pools, and is safe for use on live, energized electrical systems up to 100,000 volts.

⚙️ Why Upgrading to the Amerex 423 Brass Valve Matters
-
Exceptional 10-A:120-B:C Fire Rating: This means it suppresses up to 10 times the fire volume of a basic 1-A rated unit on ordinary combustibles, and up to 120 square feet of flammable liquid fire.
-
Corrosion-Proof Brass Valve: While aluminum-valve models like the Amerex A411 are excellent for indoor office spaces, the brass valve on the Amerex 423 is mandatory for marine applications, coastal docks, and industrial washdown areas.
-
Extended 30-Second Discharge: The massive 20 lb cylinder provides an extended discharge window, allowing the operator more time to thoroughly cover and suppress fast-moving commercial fires.
-
USCG Approved with Heavy-Duty Bracket: Fully approved by the United States Coast Guard for maritime use when paired with the heavy-duty Model 810 vehicle/marine bracket (sold separately).
