Propylene, Propane, and Acetylene - Fuel Gas Choices


Alternative fuel gases are suitable substitutes for Acetylene. In many cases, preferred substitutes.

  • Propylene can be faster than Acetylene in many applications - it can also be more cost effective. Generally speaking, Propylene can be expected to perform as well as, and even better than, Acetylene. 
  • Propane does not have the same BTU values as Propylene, but in the right applications, Propane has its own advantages over Acetylene. 
  • Propylene and Propane do not require chemical stabilization. Each cylinder contains more pounds of usable fuel gas.


Making the move from Acetylene to Propylene or Propane (there are other choices too) will require some small adjustments, but not a measurable change in the way you work.

  • To get the most out of Propylene and Propane, we recommend that you use a torch designed for higher pressure operation. 
  • Along the same lines, your gas pressure regulators need to be designed for the gas and the pressure you are using.
  • For optimum results and safety, MATHESON recommends the use of tips specifically designed for alternative fuels. 
  • Acetylene hoses are not suitable for use with alternative fuels - Grade T hoses are required. 
  • Choosing and using the right hardware is not just a matter of productivity ... it's also a matter of operator safety. We can work with you on equipment recommendations and PPE choices as well.


MATHESON Gas Professionals have been trained in the application requirements of all gases. They can help make your transition to alternative fuel gases a smooth one.
