    Interchangeability

      The socket and plug are interchangeable irrespective of the type of
      connections.

     
    Precaution
    1. The minimum hole diameter of the embedded plug is set to the outer diameter of the socket. Before machining a hole, check the size of you clamping tool. A box driver conveniently serves as a clamping tool.
    2. Hitting the CUPLA may reshlt in leakage (due to brass construction).
    3. Do not forcibly rotate CUPLA when it is connected.
      Connect a nipple for deeply embedded PF type plugs.
    4. Use Vition packings when operating temperaturess may exceed 80℃
