Specifications for Variant SKU: 2MS3-PL Dixon
Series: M-Series
Shape (Orientation): Straight
Ends Configuration: 1/4in Female ARO 210 QD Interchange, 3/8in Hose Barb
Material(s): Nickel-Plated Brass, Steel

Compatibility & Interchange:
  • ARO 210
  • Hansen 210/310
Construction:
  • Machined components are manufactured using solid bar stock.
  • Stainless steel springs. Carbon steel balls and retaining rings.
  • Nitrile (Nitrile Rubber) seals are standard. Providing a temperature range of -40°F to 250°F (-40°C to 121°C).
  • Steel componentry is plated using ROHS Compliant Trivalent Chrome.
Safety Notes:
  • Operating pressure for couplings utilizing hose barb connections may be dramatically reduced to that of the hose rating and/or hose end connection combination. Consult hose manufacturer's catalog for hose end connection ratings. If in doubt, test under controlled conditions for suitability to application.
  • Dixon cannot assume liability for misapplication of production resulting in equipment down-time, lost production, and/or personal injury including death.
  • It is important to be safe when installing quick disconnect couplings into a pneumatic circuit. Never install a pneumatic coupling directly into an air tool, use a piece of hose that is at least 18" long, between the tool and the coupling, to prevent damage to the coupling. To protect the operator, safety devices, such as a safety check valve and safety cable should be installed in case there is a hose or coupling failure.
