Better known as Freon, R-12 is an awesome refrigerant used in automotive air-conditioners and refrigeration applications. If you happen to own/drive a vehicle with an air-conditioner that is factory charged with R-12 Freon, and the systemworks good and does not leak, DO NOT UNDER ANY CIRCUMSTANCES MESS WITH IT. Pretty much any vehicle manufactured prior to 1993 is guaranteed to have an R-12 A/C system, but some 1993 vehicles came with the new stuff. It all depends on the manufacturer. Any vehicle manufactured prior to 1993 is guaranteed to have an R-12 air-conditioning system from the factory, with some exceptions. I have seen 1993 vehicles with R134a and early 1994 vehicles with R-12. Dichlorodifluoromethane (R-12), is a colorless gas, and usually sold under the brand name Freon-12, is a chlorofluorocarbon halomethane (CFC), used as a refrigerant and aerosol spray propellant. Complying with the Montreal Protocol/Clean Air Act, its manufacture was banned in the United States along with many other countries in 1994 due to concerns about damage to the ozone layer. R134a is R-12's replacement, and has been used in automotive and refrigeration applications since 1994-1995. You will begin to realize that R-12 is the superior refrigerant when you are idling in a parking lot or stuck in a traffic jam. While an R-12 system will almost always blow cold air no matter what, R134a begins to blow merely cool air when the vehicle is not moving.
True stories of R-12's superiority:
The A/C in my dad's 1983 Toyota Celica was absolutely freezing! Gotta love that R-12! The air-conditioner in my mom's 1990 Toyota Camry was the same way, as was the A/C in my dad's 1992 Dodge Dakota, and in his 1993 Chevy S-10 Blazer. R-12 is just a far superior refrigerant to R134a.
A friend of mine put some cans of soda in his old 1980s fridge that uses R-12, and the soda got so cold and frosty that some of the cans actually burst!

Get the R-12 mug.One day a man walks into a bar and to his amazement, he finds a tiny person playing a tiny
piano. Stunned the man asked the bartender where he got this amazing person. The
bartender replied that inside the closet there is a genie that will grant him a single wish.
The man dashed into the the closet and as the bartender said, there was a genie inside.
Without hesitation the man wished for a million bucks, but instead 1 million ducks
instantly appeared. Infuriated the man stormed to the bartender and screamed
"I think your genie is hard of hearing, I asked for a million bucks but instead I got a million ducks."
The bartender shook his head and replied, "You're telling me... Do you really think I asked for a 12 inch pianist?"

Get the August 12, 2036 mug.A shotgun, designed in America but produced in South Korea, that was made in both full-auto and semi-automatic versions. Only the semi-automatic USAS-12's were ever imported into the United States.
The USAS-12 was reclassified as a Destructive Device in the early '90's, requiring registration with the BATFE and special requirements for sale and transfer to other civilians. There was an amnisty during the 1990's for registration, but that anmnisty has since been closed and all non-registed USAS-12's are illegal contraband.
Accepts 20 round Drum magazines; 10 round "stick" or "box" magazines and 12 round box magazines. The 12 round box magazines are extremely rare and the 20 round Drum magazines are rare but possible to obtain.
Generally referred to as: "M16 on Steroids" because it looks like a big, thick M16. Also sometimes refered to as a "Street Sweeper" and/or "Lead Hose" because of the amount of lead the gun is capable of delivering in a very short period of time.
