Model RT A400 - Halon 1211-1301 Blend
Typical use: Cockpit/Cabin.

The gaugeless RT A400 is the smallest Halon fire extinguisher available anywhere. It's a great flight bag accessory.

These extinguishers contain a unique blend of liquefied gas 1211/1301, two highly effective fire fighting agents. These units are self expelling which means that the pressure remains constant even when the extinguishers are almost empty.

Shipped promptly and received in excellent condition. I fit-checked the unit to my airplane and its just as expected. Will install soon. I also read the instructions and will weigh the core unit annually to make sure its fully charged. Very good product for small airplanes from the limited experience I have with it. Lets hope I never have to use it.

My RT A400 is holding up as advertised...I bought it in 2012 and after 7 years, it still weighs the same original 1.2 lbs. and no signs of leaks.

Saved my plane from burning to the ground when battery wires contacted each other and caught fire. Well worth the money!

I had this model for some time mounted in between the seats of my RV6. Well, I finally really needed it! I was burning in new brake linings when a fire broke out in my right main gear. The little RT-400 did a great job putting out the fire.

Small and compact. Last on average for 8 years before it falls below the recommended weight of 500 grams. Never had one just discharge on its own.

Less than 50 hours of flight tome and the bottle self emptied, with no visible damage or marking. Weighing before every flight is simply impractical. Would not recommend this unit

It is small and lightweight, so fits well in my small experimental aircraft (Sonex). But mine has not lasted the advertised 12 year shelf life. Mine is about 6 years old and weighs less than 200 grams, meaning it has leaked all its contents. Ill probably purchase another, but not happy about the short life of this expensive extinguisher

Will not last as advertised! Agent seeps out beyond serviceable limits around the bottle and discharge head after a few years.

My RT A400 completely leaked out inside of three years after purchase. I was provided a new one at no charge, but it also leaked out within 3 years. There is a service bulletin issued against these. Recommend buying an all metal extinguisher with a gauge.

Q: We have aircrafts equipped with fire extinguisher RT A400. We checked the weight of A400. The weight was less than the standard weight. Can we recharge the agent? Otherwise should we replace the extinguisher?

The A400 is a sealed unit and cannot be re-charged.

Q: Does it matter what position the fire extinguisher is mounted in? Can i lay on side as well as vertically, without leaking?

YES! It can lay on its side. However, it must be positioned upright when in use, and not in a horizontal position.

Q: What is the warranty on this RT A400 unit?

Per the manufacturer: The standard Warranty for all our RT-A extinguishers is two years from receipt date for workmanship & quality.

Q: After the 12-year shelf life, can the manufacturer service and return to service for another 12-years?

The answer unfortunately is no, not permitted by NFPA for non-rechargeable extinguishers. The big advantage of them is that they are not subject to the 6-year teardown maintenance and hydro test required for rechargeable extinguishers resulting in huge savings!! After 12 years, they must be replaced by a new unit with the old one sent to a service Center or to the manufacturer for halon recycling.


No, this does not include the 8130-3 form. It can be requested at the time of checkout in the shopping cart.
