R134a Refrigerant: An 
Overview
WESTRON R134a:
Westron R134a refrigerant is a ubiquitous refrigerant used in 
many air conditioning applications. It is often packed in blue 
cylinders. Because of the nature of R134a's qualities as an 
HFC (hydrofluorocarbon) refrigerant, it has minimal ozone 
depletion potential and has a low greenhouse effect. R134a 
is an excellent alternative for R12, which has been employed 
in a variety of applications.
 Because of its decreased environmental impact, demand for 
R134a refrigerant and other HFCs will steadily grow. It is now 
also frequently employed in the air conditioning systems of 
contemporary automobiles. It is used in the manufacturing 
industry for plastic foam blowing. It is used as a propellant in 
the pharmaceutical business. When exposed to the 
atmosphere, it exists as a gas since the boiling temperature 
is -14.9°F or -26.1°C.
Prominent Features:
This refrigerant is not completely compatible with the 
lubricants and mineral-based refrigerants that are currently 
utilized in R-12. To use this refrigerant, design adjustments to 
the condenser and evaporator are required. The system must 
also be modified with smaller hoses and a 30% increase in 
control pressure requirements
• R134a has a high vaporization temperature.
• R134a is not poisonous, flammable, or corrosive.
• It has an auto-ignition temperature of 1418 degrees
           Fahrenheit (770 degrees Celsius).
• R134a has a critical temperature of 252 degrees
           Fahrenheit or 122 degrees Celsius.
• Because R134a has a boiling point of -15.34 degrees 
           Fahrenheit or -26.3 degrees Celsius, it exists 
boiling point should be lower than the target 
temperature.
• It is 0.11 percent by weight soluble in water at 77 
degrees Fahrenheit or 25 degrees Celsius.
• Because in the form of a gas when exposed to the 
atmosphere. This is a desirable attribute since a 
refrigerant's R134a has no Ozone layer depleting 
qualities, it became popular as a perfect substitute for 
dichlorodifluoromethane (R-12), which was known to 
deplete the Ozone layer.
• R134a has a low acidification potential.
• In liquid form, it has a modest density.
• Light blue is the generally recognized cylinder color
           designation for R134a refrigerant.
Detecting Leaks:
When you suspect an R-134a leak in your air 
conditioning system, one of the five procedures listed 
below can be used to identify it. The easiest and most 
cost-effective technique is to use soap solution. 
Workshops may employ more advanced technology to do 
this.
• Halogen Selective Detectors 
• Fluorescent Dyes 
• Electronic Leak Detectors 
• Soap Solution 
• Ultrasonic Leak Detectors
