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.
