Classic car shows might be an outlet.
Nearest big classic car show to me is in Carslile, PA. , and I ain't about to drive for 8 hours to try to sell a 30# jug of R-12.

Carlisle is a fantastic car show. It’s a fantastic township. (Spent a few days/nights there last year in the “Carlisle House B&B”…. great stay, history, museums, food, whiskey. (Whiskey Rebellion Restaurant) 😜

A quick internet search indicates it sells for as much as $100/lb. If you have 30 lbs you might be sitting on some cash. (And I was wrong in my earlier statement…. apparently R12 is still legal to use, buy, sell, or transport…. it’s only illegal to mfr’ NEW R12.

Speaking of refrigerants, if you are a "plan ahead" type and have a newer unit in your home, ya might want to pick up a jug of 410a. It's on the way out soon. Just like 22 ot will become increasingly costly.

Those "guys" buy the refrigerant to have it destroyed and then sell the carbon credits to polluters to allow them to continue polluting.

This is irritating… if I’m reading this right…. 410a, the replacement for R22…. is actually more damaging and more persistent than R22.

410a = Global Warming Potential of 2088 years and an atmospheric lifetime of nearly 30 years compared with the GWP of 1810 years and a 12-year lifetime of R-22. (and it’s potentially more hazardous to the handler due to higher operating pressures. It is cautioned that only specially-trained persons handle it.

So now 410a is being phased out…in favor of some other stuff. Grrrr….

Thank you for the heads up on that!
I bought that 30 pounder some years ago, when I was in the Bahamas.
Think I remember paying $96 for it.

R12 is still allowed to be used as a fire-extinguish agent in aircraft and submarines.

I don't know if submarines actually use R12, but ALL commercial aircraft use Halon extinguishers.

I will pay $200 for it, pick it up, and put it to good use in a 1960s car air conditioner.

Halon….also known as Dichlorodifluoromethane …also known as R12.

I’ve been operating airplanes that use it for engine fire-extinguisher-agent for 40+years.

It’s excellent for use in electrical/computer compartments…. non-damaging to those items. Perhaps nuclear subs need it?

It is most likely used as fuel to push out whatever chemical they are using for extinguishing the fire. I was told recently that halon is no longer used for fire extinguishing except in some rare places such as computer rooms.

I was not aware the Dichlorodifluoromethane = R12 = Halon
Commercial aircraft cabin extinguishers are Halon.

It may be used as a propellant but it also isolates the combustible materials (smothers). It is mostly found in older equipt. Most recent-mfr’d aviation engine-extinguishers use Nitrogen for propellant. Here’s a typical installation:

410a was never intended to be permanent in the industry. It was a bridge refrigerant. Unlike 22, 410a is chlorine free (no ozone depletion) and much more effective at moving heat. Under international law (Montreal Protocol) chlorine had to be terminated from refrigerants. Since those that abide by the Protocol have to recover/ reclaim refrigerant, the GWP of 410a was not a concern at the time.
Fun fact- the favored replacement for 410a is classified as flammable. R-454b is an A2L mildly flamable substance.

So are the extinguishers in my shop and RV. Less mess to clean up (none) and no equipment damage from the powder residue.

Absolutely true.....
I like 'em....but.....
Halon extinguishers are CRAZY expensive!

Considering the likelihood that they may ever actually be used, IMHO, the dry chemical type is vastly more cost effective.

I have dry chemical extinguishers .
1- 20lb.
4-10lb.
2-5lb.
One 2-1/2 lb.

I might need a bank loan if I were to buy those in Halon!

They are, but recovery time is lower. Especially on vehicles. That powder from ABCs can cause problems with the wiring harness down the road. It is corrosive, and more so when wet. We use the dry chemical in the garage, and CO2 + dry chemical in the kitchen (CO2 and grease fires dont mix). The truck has a DC under the seat. The shop and toy hauler where a fire is most likely to happen while working on something, is always Halon.

Stretching my memory, but seems like some commercial kitchen ventilation hood systems had Halon extinguishers in them many years ago.

If activated, they didn’t fill the kitchen with a powder-like substance.

I was around a few of those that touched off 40 +/- years ago. Might not have the right material though. Didn’t associate Halon with R12 either.
