What is the color code for refrigerant?
This guideline also recommends a universal container color of light green gray (RAL 7044) for all Refrigerants.
Originally, Guideline N stipulated different paint colors for refrigerant cylinders for quick and easy recognition, such as light green for R-22, orange for R-404A, light blue (sky) for R-134a, and rose for R-410A.
R-134a cylinders are colored light blue.
Refrigerant color codes are useful for us to recognize the type of gas that is stored in the cylinders. The name of the gas are usually labelled on the cylinders as an added aid so that we will not make any mistakes in recognizing them. Putting the wrong gas into our air conditioning systems can damage the compressors.
The dye/refrigerant mixture will escape and accumulate at all leak sites. By then scanning the system with a leak detection lamp, all leaks will fluoresce green or yellow, making them easy to spot.
R717 (Ammonia) is refrigerant grade Ammonia (NH3) used in low and medium temperature refrigeration. It is a colourless, pungent, highly toxic gas but is a very efficient refrigerant with zero Global Warming Potential (GWP).
| Number | Type | Color |
|---|---|---|
| R-22 | HCFCs | Light Green |
| R-123 | HCFCs | Light Gray |
| R-124 | HCFCs | Deep Green |
| R-401A | HCFCs | Coral Red |
Trichlorofluoromethane, also called freon-11, CFC-11, or R-11, is a chlorofluorocarbon (CFC). It is a colorless, faintly ethereal, and sweetish-smelling liquid that boils around room temperature.
R-407C cylinders are colored burnt orange. This refrigerant is intended as a replacement for R-22.
R-410A cylinders were colored rose but are no longer specially color-coded, now bearing a standard light gray color.
What is the color of R-410A refrigerant?
“Right now, I deal with four different kinds of refrigerants — R-410A, which is pink; R-22, which is green; R-407C, which is brownish orange; and MO-99, which is blue,” O'Neill said. “It's a very simple system, and it works.”
| Function | label | Color, old IEC |
|---|---|---|
| Protective earth | PE | green-yellow |
| Neutral | N | blue |
| Line, single phase | L | brown or black |
| Line, 3-phase | L1 | brown or black |
Refrigerant and Freon are gases that are both colorless and odorless.
The RGB color 169, 169, 169 is a light color, and the websafe version is hex 999999, and the color name is darkgray.
The R number of a chemical refrigerant is assigned systematically according to molecular structure. First ASHRAE digit is the number of carbon atoms minus 1 (C-1); the second digit is the number of hydrogen atoms plus 1 (H+1); the third digit is the number of fluorine atoms; any remaining spaces are chlorine atoms.
Toxic or corrosive gas – Yellow colour. Flammable gas – Red colour. Oxidizing gas – Light Blue colour. Inert gas – Bright Green colour.
Color coding's main purpose is to separate and organize. This is especially important in the food industry where cross-contamination, allergen cross-contact, and cleaning chemical strength are all concerns.
Green refrigerants such as carbon dioxide (CO2) are the present and the future of industrial and commercial refrigeration (food storage, supermarkets, etc.): these solutions have a high heat exchange coefficient, as well as being environmentally friendly as they have a low GWP (global warming potential).
The actual refrigerant is colorless and odorless. But when it is installed in a refrigeration system, it is blended with refrigeration oil. Some oils have a green tint, some refrigerant had green UV visible color added to help locate leaks.
Clear - Clear liquid is just condensation, likely from your car's A/C system, and doesn't need attention. Dark Brown - This could be old/dirty motor oil, but could also be brake fluid. Either is a major concern and needs to be taken care of ASAP. Light Brown - Light brown fluid is either motor oil or gear lubricant.
What is R744 refrigerant?
Refrigerant R744, i.e. carbon dioxide (CO2), is an environmentally friendly refrigerant. Its ODP is zero and its GWP is 1, which means that it has even less global warming potential than hydrocarbons.
Ammonia (NH3 or R717) is the refrigerant that was first used in cold steam engines around 1870. More than 100 years ago, it has been used as a refrigerant in large-scale refrigeration and industrial plants.
R-502 Refrigerant. Contains HCFC-22/CFC-115. An azeotropic mixture used in low and medium temperature refrigeration applications.
Properties of R-32
It's a colorless odorless, mildly flammable gas which is insoluble in water.
The hexadecimal color code #222222 / #222 is a very dark shade of gray.
Chlorotrifluoromethane, R-13, CFC-13, or Freon 13, is a non-flammable, non-corrosive chlorofluorocarbon (CFC) and also a mixed halomethane. It is a man-made substance used primarily as a refrigerant.
R-22 – also known as Chlorodifluoromethane – is a colorless gas that is commonly used as a refrigerant. Other names for this chemical include R-22 Refrigerant, R-22 Freon, or HCFC- 22 Freon.
The best replacement for R-22 Freon is usually R-407c. It has a very low loss in capacity (0 – 5%) relative to R-22 and is less expensive than many other R-22 replacement refrigerants.
In comparison to R407C, R410A has a higher evaporation heat transfer coefficient and a higher condensation heat transfer coefficient. The heat transmission coefficient of R410A in a smooth horizontal tube is about 50% higher than that of R407C, according to the evaporation test results.
Can you mix R22 and R407C?
Mixing R22 with R407C
According to the 609 EPA rule, mixing refrigerants is illegal and anybody caught doing so will be heavily fined.
FORANE Refrigerant: R-408A, 24 lb Container Size, Purple, Cylinder - 3L429|408A - Grainger.
The hoses are color-coded by the manufacturer to differentiate between low pressure and high pressure. The high-pressure side is red, and the low-pressure side blue. The reading of the red hose is a maximum of 999 psi. The blue hose provides a reading between 0 and 99.9 psi.
To know which type of refrigerant your air conditioner uses, take a look at the label on the compressor unit outside. It'll clearly tell you which type of refrigerant the unit uses. The newer type is R-410A, and the older type that I've been talking about is R-22, also identified as HCFC-22.
R-410A is a chlorine-free refrigerant that meets the U.S. EPA's newest, most stringent environmental guidelines. R-410A was developed as an alternative to R-22 (Freon), which will be phased out over the coming years in response to international environmental concerns.
In most cases R32 is the superior refrigerant when compared to R410A. While neither refrigerant depletes the ozone layer, R32 has a lower GWP and is easier to recycle. R32 also has lower operating and maintenance costs and is nowadays more common than R410A due to the phase out.
No. R32 is not suitable as a drop-in replacement for R410A and must only be used in systems specifically designed for R32.
A: N is for neutral (white wire) and L is line or hot (black wire).

A color hex code is a hexadecimal way to represent a color in RGB format by combining three values – the amounts of red, green and blue in a particular shade of color. These color hex codes have been an integral part of HTML for web design, and remain a key way of representing color formats digitally.
What is the most common color of coolant?
Most people think of antifreeze or coolant as green. For years many antifreeze/coolants were green in color but now many coolants come in a variety of colors. Antifreeze or coolant can be yellow, pink or red, blue, and green. The color of the antifreeze/coolant is really based on the formula.
Variations of coolant/antifreeze can come in; pink, red, orange, blue, green, and yellow. This can make it confusing when trying to decide which coolant you need in your vehicle. The different colors can mean different properties of the liquid.
The color of healthy engine coolant is green (for ethylene glycol) or orange (for Dexcool). A rusty color indicates that the rust inhibitor in the coolant has broken down and it can no longer control rust and scale buildup.
216 is a dark green paint colour. Appearing as an off black in certain light, Obsidian Green 216 is a popular green colour for front doors, railings and increasingly used indoors in kitchens, living rooms and bedrooms for dramatic effect.

Popular solid colors used for color-coding are black, white, yellow, purple, green, orange, grey, blue, and red. 2) Select consistent colors for each area. Try to choose colors that make the most sense in each area – like red for quality issues. Don't use the same color for equipment, sanitized, raw, processed, etc.
