The Simpson GFC34 Fuel Cell is a purpose-built power source for gas-actuated concrete nailers, engineered by Simpson Strong-Tie to deliver consistent, repeatable firing performance across demanding job-site conditions. Designed for compatibility with the GCN-MEPMAG and GCNMEP concrete nailers, as well as many major-brand gas-actuated concrete nailer tools, this fuel cell keeps crews productive on both commercial and residential fastening applications - from concrete slab work to masonry installations.

Key Features

• High shot count per cell - Each GFC34 provides up to 1,200 shots, meaning fewer interruptions mid-project and less time spent swapping out fuel cells on high-volume fastening jobs.
• Wide operating temperature range - Rated for use between 20 deg. Fahrenheit and 120 deg. Fahrenheit (-6 deg. Celsius to 49 deg. Celsius), this fuel cell performs reliably in cold winter conditions and hot summer environments alike, so crews are not slowed down by seasonal temperature swings.
• Broad tool compatibility - Engineered for the Simpson Strong-Tie GCN-MEPMAG and GCNMEP nailers and compatible with many major-brand gas-actuated concrete nailer tools, making it a practical fit for job sites where multiple tool brands are in use.
• Purpose-built for concrete and masonry fastening - Formulated specifically to power gas-actuated concrete nailers, delivering the consistent combustion needed for precise, repeatable fastening into concrete and masonry substrates.

Why This Product

• Fewer stops, more output - A 1,200-shot capacity per fuel cell makes the GFC34 a strong match for large-scale or high-volume fastening projects where workflow continuity matters.
• Year-round reliability - The broad temperature performance window means contractors can rely on consistent nailer operation whether working in a cold-weather pour or a summer concrete application - without sourcing a different fuel cell for each season.
• Versatile across brands - Compatibility with many major-brand gas-actuated concrete nailer tools means the GFC34 can serve mixed-fleet job sites, reducing the number of different fuel cell SKUs a contractor needs to keep on hand.
• Backed by Simpson Strong-Tie engineering - Designed by a manufacturer with deep roots in structural fastening and concrete anchoring applications, giving contractors confidence that the fuel cell is matched to the performance demands of real construction environments.
