Specifications for Variant SKU: 8WBF8-B Dixon
Series: W-Series
Shape (Orientation): Straight
Ends Configuration: 1in Female ISO-7241 Wing Nut QD Interchange, 1in Female BSPP
Material(s): Brass, Steel
Seal Material(s): Buna-N/Nitrile Rubber
Compatibility & Interchange:
  • Danfoss Eaton Aeroquip 5100-Series, Parker 6100-Series
  • Snap-Tite 78-Series, Faster Series-FB, Safeway S51-Series
Features:
  • Full Hex - Ease of Installation.
  • Compact Body Profile - Reduction of Side-Load Stress.
  • Hybrid Valve Guide - Improved Flow & Pressure Performance.
  • Anti-Extrusion Seal-Pack - Superior Longevity.
  • Bonded Flange Valve - Improved Pressurized Connection Service.
Construction:
  • Machined components are manufactured using solid steel and brass bar stock.
  • Stainless steel retaining rings and springs maximize corrosion resistance and extend service life.
  • Steel componentry is plated using ROHS-compliant trivalent chrome.
  • Rugged steel wing nut for threaded connect and disconnect operation.
  • For steel models, coupler valve sleeve and plug valve are constructed of brass.
Seal Components:
  • Nitrile seals are standard, providing a temperature range of -40°F to 250°F (-40°C to 121°C).
  • Couplings have a TPC-ET back-up ring on the main coupler valve sleeve to extend service life.
  • Main coupler valve has a bonded face-seal to improve seal integrity during pressurized connection/disconnection.
  • Plug valve seal is crimped to improve seal integrity and prolong service life; 1-1/2" has bonded plug valve.
  • External O-ring on plug indicates full connection and acts as a contamination shield in connected mode.
  • Redundant O-ring on the coupler body will engage plug for secondary sealing support.
Safety Notes:
  • Although wingstyle couplings are able to connect and disconnect while under pressure, it is recommended that hydraulic power supply be de-energized during connection to ensure operator safety. If it is not possible to de-energize the circuit, operators must be aware of their surroundings to ensure that an attachment or tool does not put them at risk, once hydraulic power is applied during the connection process.
  • W-series couplings are not recommended for continuous hydraulic impulse applications at rated pressures.
