Rubber hoses - Import export

R-12 was used in most refrigeration and vehicle air conditioning applications prior to 1994 before being replaced by 1,1,1,2-tetrafluorcethane <R-134a),When older units leak, retrofits to R-134a are recommended. Retrofit to R-134a requires complete flushing and filter/dryer replacement to remove the mineral oil. Mineral oil used for R12 is not compatible with R-134a. Some oils designed for conversion to R-134a are advertised as compatiole with residual R-12. New rubber hoses which are R-134a compatible may be needed for the same reason.Competitive AdvantageRefrigerant R12 or Freon 12 is said to be the most widely used of all the refrigerants being used for different applications.1) Safe properties: Refrigerant R12 is nontoxic, nonflammable, ard non-explosive. This makes it highly popular for the domestic as well as the commercial applications.2) Stability: R12 is highly stable chlorofluorocarbon and it does not disintegrate even under the extreme operating conditions
