The SF-ABC340 distinguishes itself within the 5 lb. class by delivering a significantly higher 40-B flammable liquid rating compared to the SF-ABC310's 10-B rating — making it the preferred choice when flammable liquid and gas hazards are a primary concern on the job site. Its 195 PSI charge, 14.5-second discharge time, and extreme temperature range of -65°F to 120°F ensure reliable performance across demanding outdoor and indoor environments. Manufactured by Strike First, a company with over 35 years of fire equipment manufacturing experience, the SF-ABC340 is built to NFPA 10 and D.O.T. requirements for broad compliance.
Key Features & Benefits
Modified Universal Valve Body
The modified universal valve body accepts both pin and fork wall hooks, giving contractors flexibility in mounting configurations across different job site setups. This reduces the need to source separate hardware for different bracket types.
Oversized Pull Pin with Retaining Strap
The oversized pull pin with retaining strap is engineered for easier and faster activation under stress — critical when seconds count in an emergency. This design reduces fumbling during high-pressure situations, improving response time.
Waterproof Stainless Steel Gauge
The waterproof stainless steel pressure gauge maintains readability and accuracy in wet, dusty, or corrosive job site environments. Contractors can perform quick visual pressure checks without concern for gauge degradation over time.
Super Durable Polyester Powder Paint Finish
The steel cylinder is finished with a super durable polyester powder paint coating that provides superior corrosion resistance. This extends the service life of the extinguisher in harsh outdoor or high-humidity environments.
Full Grip Hardcoat Anodized Aluminum Handle
The reinforced, full grip hardcoat anodized aluminum handle provides a secure, comfortable hold during discharge. The hardcoat anodizing adds durability and resistance to wear from repeated handling and storage.
Color and Bar Coded Labels
Color and bar coded labels support accurate service and inspection tracking, simplifying compliance with NFPA 10 service record requirements. This is particularly useful for contractors managing multiple extinguishers across large job sites.
Extreme Temperature Range
Rated from -65°F to 120°F (-54°C to 49°C), the SF-ABC340 remains operational in extreme cold and heat conditions. This makes it suitable for year-round use in northern climates, cold storage facilities, and hot outdoor environments.
Common Applications
