IAPP Series

ISO A Push-Pull Quick Couplers (1/2″ ISO A For Agricultural and forest equipment)

AKJia’s IAPP Series ISO A couplers are designed primarily for the agricultural industries and incorporate a push-pull design. The coupler is panel mounted using circlip grooves in the locking sleeve. The Push Pull hydraulic coupling performs
well on installing a hose to connect. They can connect under pressure.


  • Carbon steel with trivalent plating
  • Zinc Nickel Plating is option
  • Female half available in ‘Push Pull’ design
  • Fitted with Nitrile seals

Push-pull quick couplings are a type of quick coupling that, as the name suggests, are connected and disconnected with a simple push and pull motion. They offer a convenient, efficient, and secure way to quickly join and separate hydraulic lines without the need for tools. The connection is complied with ISO 7241 Series A and 1/2″ body size.
