Atlas Copco Hydraulic Quick Couplers

Source the right quick-disconnect couplings for Atlas Copco machines — attachment lines, implement outlets and service replacements.

Atlas Copco Machines and Their Hydraulic Quick Couplings

Atlas Copco builds air compressors, construction equipment, drilling rigs and industrial tools. Atlas Copco industrial and construction machines commonly use ISO 7241 ball-lock couplings on hydraulic circuits; newer equipment may use flat-face on high-flow auxiliary lines. Threads vary by market.

Coupling Profiles You Will Find on Atlas Copco Equipment

The table below summarises the quick-coupling profiles most commonly used across Atlas Copco machine families. It is a field guide, not a guarantee: verify the profile on your specific machine before ordering.

Selection Notes for Atlas Copco Fleets

  • Atlas Copco industrial machines commonly use ISO 7241 ball-lock couplings.
  • Newer drilling and construction equipment may use flat-face on auxiliary lines.
  • Threads split by market: NPT in North America, BSPP in Europe/Asia.

Replacement and Service Guidance

For Atlas Copco equipment, confirm the coupling profile (ball-lock vs flat-face) and the thread per market. Provide the model and a photo of the halves.
