FK-5-1-12 vs Novec 1230: Are They the Same Thing?
Share
If you've spent any time researching clean-agent fire suppression, you've seen both names thrown around — sometimes in the same sentence, sometimes as if they're competing products. So which is it? Are FK-5-1-12 and Novec 1230 two different things you have to choose between, or the same thing wearing two names?
Here's the short answer up front: they're the same chemical. Novec 1230 is a brand name; FK-5-1-12 is the generic name for the chemistry inside it. But that simple answer hides a story worth understanding — especially now, because the brand you may know is being phased out while the chemistry itself carries on. This article clears up the confusion and explains what it means for anyone specifying or buying a clean agent today.
The Simple Answer: Same Chemical, Different Names
Novec 1230 was 3M's trademarked brand name for a fire suppression fluid. The actual chemical inside that product is FK-5-1-12, identified by CAS number 756-13-8. So "Novec 1230" and "FK-5-1-12" refer to the same substance — one is the marketing name, the other is the chemical name.
It's the same relationship you see everywhere in consumer products. Think of it like a brand-name medication versus its generic equivalent: same active ingredient, different label. When someone says "Novec 1230," they're really saying "3M's version of FK-5-1-12."
This matters because a lot of confusion online treats them as rivals — "FK-5-1-12 vs Novec 1230," as if you're weighing two options. You're not. You're looking at one agent that happens to be sold under both a brand name and its generic name.
Why There Are Two Names in the First Place
So why the dual identity? It comes down to how the chemical reached the market.
3M developed and commercialized the fluid and sold it under the Novec 1230 brand, backed by heavy marketing. For years, Novec 1230 became the name people knew — to the point that many in the industry used "Novec 1230" as shorthand for the entire category, the way people say "Kleenex" for tissues.
But FK-5-1-12 is the standardized generic designation — the name used in technical standards, regulatory listings, and by the many other manufacturers who also produce the agent. It's the neutral, brand-independent term. That's why you'll see FK-5-1-12 on safety data sheets, in NFPA 2001 clean-agent standards, and on the EPA's SNAP program listings, while "Novec 1230" appears in 3M's product literature.
Two names, then, for two reasons: one is a company's brand, the other is the industry's generic label.
The Big Change: 3M Is Discontinuing the Novec 1230 Brand
Here's the development that makes this question so common right now. In December 2022, 3M announced it would exit per- and polyfluoroalkyl substance (PFAS) manufacturing and discontinue the use of PFAS across its product portfolio by the end of 2025. As part of that broad corporate initiative, 3M is discontinuing its 3M Novec 1230 Fire Protection Fluid.
This is where people understandably panic and assume the agent itself is going away. It isn't. Two points are essential to understand:
The brand is being discontinued, not the chemistry. 3M is stepping away from making Novec 1230, but FK-5-1-12 — the underlying chemical — continues to be manufactured by other chemical companies around the world.
FK-5-1-12 is not generally banned in the U.S. It remains available from multiple suppliers and continues to be listed under the EPA's Significant New Alternatives Policy (SNAP) program for specified applications. So the agent has a supply path well beyond 3M.
In other words: "Novec 1230 discontinued" does not mean "FK-5-1-12 discontinued." The label is going away; the chemistry is staying.
What This Means If You Need a "Novec 1230 Alternative"
Because the Novec 1230 brand is being phased out, a lot of people are now searching for a Novec 1230 alternative. And here's the slightly surprising answer: the most direct replacement for Novec 1230 is usually FK-5-1-12 itself — just sourced from a manufacturer other than 3M.
Since Novec 1230 was FK-5-1-12, switching to another supplier's FK-5-1-12 means keeping the exact same chemistry and performance, only under a different brand or generic name. You're not compromising on the agent; you're changing the label on the drum.
One important caveat for existing systems: if you have a UL Listed or FM Approved system originally filled with 3M Novec 1230, replacing the agent with FK-5-1-12 from a different manufacturer should be done only with the consent of the system manufacturer. Approvals are tied to the tested configuration, so don't swap agents in a listed system without checking.
Is FK-5-1-12 (Novec 1230) a PFAS?
This question comes up constantly alongside the naming confusion, so it's worth addressing briefly. The honest answer is that it depends on the definition used. Under broad structural definitions of PFAS — such as the one applied in parts of the European Union — FK-5-1-12 can be classified as a PFAS, because of its fluorinated molecular structure.
That said, FK-5-1-12 has a very different environmental profile from the legacy "forever chemicals" like PFOA and PFOS that most PFAS concern centers on. It has a short atmospheric lifetime, zero ozone depletion potential, and a global warming potential of less than one. We cover this in depth in our dedicated article, Is Novec 1230 a PFAS?

How FireXNull Uses FK-5-1-12
At FireXNull, FK-5-1-12 is the agent inside our fire suppression products — but we use it differently from traditional cylinder-and-nozzle systems. Rather than storing the agent in a pressurized tank plumbed to nozzles, we encapsulate it in heat-activated microcapsules that release the agent directly at the source of a fire, with no power, wiring, or sensors involved.
That approach is described on our fire suppression technology page and our FXN Microcapsules page. The finished products — FXN Tape, FXN Sticker, and FXN Rope — put the same clean-agent chemistry to work inside electrical enclosures, panels, and equipment. The advantages that made FK-5-1-12 popular in the first place — electrically non-conductive, residue-free, effective by absorbing heat — are exactly what make it a strong fit for protecting electronics and electrical systems. You can read more about those benefits in our post on clean agent fire extinguishers.
Quick Reference: FK-5-1-12 vs Novec 1230
To settle it clearly:
- Same chemical? Yes. Novec 1230 is 3M's brand name for FK-5-1-12.
- CAS number? 756-13-8 (the same for both).
- Which name is "official"? FK-5-1-12 is the generic designation used in standards and regulations; Novec 1230 is a trademark.
- Is Novec 1230 discontinued? The 3M brand is being phased out as part of 3M's PFAS exit.
- Is FK-5-1-12 discontinued or banned? No. It's still made by other manufacturers and remains listed under EPA SNAP for specified applications.
- Best Novec 1230 alternative? Typically FK-5-1-12 from another supplier — same chemistry, different brand.
The Bottom Line
FK-5-1-12 and Novec 1230 aren't two competing agents — they're one agent with two names. Novec 1230 was simply 3M's brand for FK-5-1-12, and now that 3M is exiting PFAS manufacturing, the brand is winding down while the chemistry continues through other producers.
If you've been running Novec 1230 and worrying about what comes next, the reassuring reality is that the agent itself lives on. And if you're evaluating clean-agent protection today, understanding that these two names point to the same chemistry cuts through a lot of the noise — letting you focus on what actually matters: choosing the right agent, and the right delivery method, for what you need to protect.
This article is general information, not legal or regulatory advice. Regulatory treatment of FK-5-1-12 varies by jurisdiction and changes over time. EPA SNAP listing for specified applications does not constitute EPA approval or certification of any finished product. Always confirm compliance and system approvals for your specific use and location.
