Detail Information
EH 66 Series – ISO 5675 Poppet Valve Hydraulic Quick Disconnect Couplings (Steel)
Engineered for zero-spill performance in demanding hydraulic circuits, the EH 66 Series features flat-face poppet valve couplings that outperform traditional ball-valve designs in sealing reliability and contamination resistance.
Constructed from zinc-plated carbon steel, these robust couplings deliver superior durability and corrosion protection—ideal for agricultural, construction, and industrial mobile equipment.
Key Advantages:
True flat-face design minimises fluid loss and prevents air ingress
Poppet valve mechanism ensures leak-free connection/disconnection
Higher sealing integrity compared to ball-type couplers (e.g., EH 68 Series)
Full compliance with the ISO 5675 standard across all sizes
Interchangeability by Size:
All sizes: Directly interchangeable with Parker 4000, Faster NV, Dixon AG, Eaton Aeroquip FD42, DNP PDV1, Stucchi IRV, Safeway S20, and VossWinkel ID series
½" body size only: Also compliant with ISO 7241-A
Note: The ¾" size of Faster NV series differs from Parker 4000 ¾"—verify dimensional specs before interchange.
Whether you're upgrading legacy systems or designing new hydraulic circuits, the EH 66 Series offers a high-performance, globally compatible solution that reduces downtime and maintenance costs—without compromising on quality.
