Stucchi VR Series


  • Interchangeable with the German market

Product Catagory Features:

  • Series: VR German Screw Coupler
  • Available in four sizes 3/8, 1/2, 1, 1 1/4 inches, covering the various
    fields of hydraulic applications.

  • The series VR couplings are mostly
    used in mobile cranes, trucks and industrial plant applications.

  • Screw-on system ensures connection with some residual pressure
  • Friction ring to prevent accidental Disconnection
  • Low leakage screw coupling
  • Wide range of port options

Stucchi: VR Series Overview

  • Due to their rugged design, VR
    series couplings are particularly
    well suited for heavy-duty service

  • The VR coupler is
    a durable product using a low
    leakage style valve for the sealing
    mechanism and threads as the
    mechanical connection.

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 and various seals

  • Screw-on system
    ensures connection under
    residual pressure

  • VR Series is the screw coupling series with a special sealing mechanism that minimizes the loss of oil during the disconnection.
  • This coupling is made of high strength steel with Cr III zinc plating and NBR sealing
  • These products are particularly well suited for the application of on-road vehicles in areas where limited spillage is mandatory.
  • They are available in sizes 3/8, 1/2, 3/4, 1 and 1-1/4”.
  • Available with metric threads (DIN 2353 / ISO 8434-1), BSP (DIN 3852) or other on request.


  • Connection under residual pressure is allowed in one half of the coupling up to 10 MPa (4 MPa for size 1-1/4)
  • Robustness and ease of construction.
  • Special valves ensure a good seal of the coupling disconnected and minimize spillage of fluid.
  • Shape of internal parts is designed to reduce turbulence and pressure drop.
  • Good mechanical resistance.
  • Compact design.
  • Simple to use.
