German Interchange
Screw Coupler
Stucchi VR Series

Interchange:

• 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
  conditions.

• 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.

Benefits

• 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.
