Demolition & Heavy Excavators : HQ Series

Standards : ISO 16028 (2006)

Applications :

HQ Series couplings are designed for use in excavatorhammer circuits and other applications involving high pressure pulses. Construction plant, mobile equipment, general industrial, nuclear, mining and agricultural.

Advantages :

  • Flat mating faces are easily wiped clean to prevent the ingress of contaminants
  • Improved flow path minimize the pressure drop
  • Non-spill design avoids fluid loss during connection and disconnection
  • No air intrusion during connection
  • Locking sleeve prevents accidental disconnection
  • Zinc nickel surface treatment eliminates chrome 6 and exceeds 200 hour salt spray tests to white rust
