Steel DN 6.3 hydraulic coupling socket with G 1/4 inch female threads. They are typically used for liquid lines to quickly connect and disconnect secure connections.
The G 1/4 inch female threads allow for it to be threaded onto a matching male threaded part. The maximum operating pressure is 250 bar (3625 psi). The coupling is suitable for temperatures between -20 to 100 °C (-4 to 212 °F). The seal material is NBR. The steel housing has a galvanic zink plated surface protection. The coupling complies with the ISO 7241-1 A standard.
Pros:
- Streamlining design of the flow rate range
- Push-Pull design: Coupling can be decoupled by pushing or pulling the sleeve
- Adheres to ISO 7241-1 A worldwide standard
- Can be combined with other manufacturers, such as Parker, Rectus, Cejn, Stucci, Faster or Snap-Tite
