Dixon Valve & Coupling
Hydraulic Coupling: E-Series Straight-Through Interchange Coupler (Hose Barb)
Specifications for Variant SKU: 4ES4-B Dixon
Series: E-Series
Shape (Orientation): Straight
Ends Configuration: 1/2in Hose Barb, 1/2in Female Straight-Thru QD Interchange
Material(s): Brass
Seal Material(s): Buna-N/Nitrile Rubber
Compatibility & Interchange:
  • Straight-through pressure-wash interchange
  • Parker ST-Series, Foster FST-Series, Hansen ST-Series
Features:
  • These couplers have no internal valves, providing maximum flow with minimum pressure drop.
Construction:
  • Machined components are manufactured using solid steel, brass, or 303 stainless steel bar stock.
  • Stainless steel balls, retaining rings, and springs maximize corrosion resistance and extend service life.
  • Steel componentry is plated using ROHS-compliant trivalent chrome.
  • 1-1/4" to 2" brass couplers have steel sleeves as standard to maximize service life, hardened to resist deformation.
  • Steel plugs are hardened to provide heavy-duty performance.
Seal Components:
  • Nitrile seals are standard, providing a temperature range of -40°F to 250°F (-40°C to 121°C).
Safety Notes:
  • Do Not Disconnect with pressure in line.
  • Dixon cannot assume liability for misapplication of products resulting in equipment down-time, lost production, property damage and/or personal injury including death.
  • Operating pressures for the standard hose barbs utilizing hose barb end connections may be dramatically reduced to that of the hose rating and/or hose and end connection combination. Consult hose manufacturer's catalog for hose end connection ratings. If in doubt, test under controlled conditions for suitability to application.
