The 1619-3803-00 Atlas Copco OEM Drive Coupler is an OEM Stromag Periflex-style coupling for Atlas Copco portable compressor platforms. This coupling mounts directly to the engine flywheel and provides torsional damping through a flexible disc tire element.
Atlas Copco uses Periflex couplings in portable compressor models where the flywheel-mount design suits the driveline architecture. The disc tire can be serviced independently without moving the engine or airend, making field maintenance faster. The coupling handles the torsional loads of Atlas Copco’s diesel-driven portable platforms used in construction and industrial applications.
The 1619-3803-00 is a direct factory replacement. Install per Atlas Copco’s service procedure, ensuring the disc tire engages the connection ring fully before returning to service.
Available from Stark Industrial Products for Atlas Copco portable compressor maintenance.
