R134a (1,1,1,2-Tetrafluoroethane), R-134a, Genetron 134a, Suva 134a, HFC-134a, HFC134a, Dymel 134a or Norflurane, is a haloalkane refrigerant with thermodynamic properties similar to R-12 (dichlorodifluoromethane), but with less ozone depletion potential.
R134a is also being considered as an organic solvent suitable for extraction of flavor and fragrance compounds, as a possible alternative to other organic solvents and supercritical carbon dioxide. It can also be used as a solvent in organic chemistry, both in liquid and supercritical fluid. It is used in the resistive plate chamber particle detectors in the Large Hadron Collider. It is also used for other types of particle detectors, e.g. some cryogenic particle detectors. It can be used as an alternative to sulfur hexafluoride in magnesium smelting as a shielding gas.
R134a is also being considered as an alternative to sulfur hexafluoride as a dielectric gas. Its arc-quenching properties are poor, but its dielectric properties are fairly good.
An additional use of R134a is as a propellant. It is used in this way mainly for gas-powered airsoft guns. The gas is often mixed with a silicon-based lubricant to assist with maintaining functionality of the airsoft gun.
