ISO 14541
Stucchi VD Series

ISO 14541 interchanges:

  • Stucchi VD Series
  • Faster CVV & CVLS Series
  • Voswinkel HS Series
  • Stauff HS Series
  • Holmbury HS Series
  • Argus Alfagomma HDK Series
  • Manuli MQS SG Series


  • Mostly used in mobile crane, vibratory hammer, oil patch and industrial plant applications.


  • O-ring connected marker is highly visible during connection and helps to keep containments out of the threads while connected
  • Series: VD European Screw Coupler Available from size 1/4 to 1-1/4 inch to cover the various fields hydraulic applications.
  • Screw-on system ensures connection with some residual pressure
  • Friction ring to prevent accidental Disconnection
  • Hardened valve bodies for impulse applications


  • Due to their rugged design, VD
    series couplings are particularly
    well suited for heavy-duty service
    conditions making them one of
    the most popular designs in

  • The VD coupler is a durable product using a poppet style valve for the sealing mechanism and threads as the mechanical connection.
  • Highly versatile design is ideally suited for hydraulic systems experiencing pressure spikes or impulses.

Technical Characteristics

  • Coupling body: zinc plated steel
  • Nipple is zinc plated hardened steel
  • Seals: Nitrile
  • Anti-extrusion rings are Teflon
  • Internal components purposely designed to
    reduce turbulence

  • Wide range of ports on request
  • Metal shoulder to protect the o-ring seal on female coupling
  • Screw-on system ensures connection under residual pressure
  • Connection is allowed with residual pressure in one side of the coupling (max 100 bar in one side).
  • The poppet valve with elastomer seal provides maximum sealing of the couplings when disconnected.
  • Shape of internal parts is designed to reduce turbulence and pressure drop.
  • The modular design allows for broad range of port configurations.
  • External O-ring indicates if the product is fully connected, prevent accidental disconnection and protect coupling against dirt.
  • Male body sealing surface protected by the threaded sleeve.
  • High resistance with impulse pressures.
  • Compact design.
  • Simple to use.
