Special Service Fittings

Special fittings are used on HFC systems to prevent mixing of non-HFC refrigerants in HFC units. These fittings are located in three places on refrigeration systems:

  • Low side near the compressor suction service valve (or suction adapter)

  • High side near the compressor discharge service valve (or discharge manifold)

  • Receiver Tank
