Tecumseh AG 4568 P-TZ (Old Code: TAG 4568 Z) 6 Hp R-404A Refrigeration Compressor

The TAG 4568 Z compressor by Tecumseh (France), well known in commercial refrigeration, is now produced under the code AG 4568 P-TZ following the brand's global catalogue update. The code change is only a naming standard: housing dimensions, rotalock valve connections and cooling capacity are identical. You can fit this original compressor with its new code in place of a failed TAG 4568 Z as a direct drop-in, without modifying the chassis or the fittings.
