Pressure loss in MPa {kgf/cm2}• Polytetrafluoroethylene (PTFE) body gives excellent resistance to chemicals.
• Both socket and plug have built-in automatic shut-off valves that prevent fluid
from outflowing when disconnected.
• No dissolution of metal ions from part in contact with liquid ensures excellentreliability.
• All components are cleaned, assembled, inspected and then packed in a clean room.
• Appropriate model can be selected form a wide variety of sizes to suit yourapplication / fluid.
• Optional keyway lock to prevent incorrect connection.
10 keyway patterns are available.

The model name {SCT-□S (P)} with the same digit in □ are interchangeable regardless ofend configurations.

* Plug or socket with female ISO Rc end configuration has V-groove on the body as identification. (In case of female NPT thread, no V-groove on either plug or socket body).
* Please inquire for other end configurations other than female thread (e.g. flanged or male thread).
Before use, please be sure to read “Safety Guide” described at the end of this book and “Instruction Sheet” that comes with the products.
