Dixon Valve & Coupling
Pneumatic Coupling: U-Series Automatic Universal Coupler (Male Threads)
Specifications for Variant SKU: 3UM3-B Dixon
Series: U-Series
Shape (Orientation): Straight
Ends Configuration: 3/8in Female Semi-Universal QD Interchange, 3/8in Male NPTF
Material(s): Brass
Seal Material(s): Buna-N/Nitrile Rubber
Compatibility & Interchange:
  • 2U-Series: 2U-Series 6-in-1 (ARO 210, Industrial, Truflate, Lincoln, Italian, and CEJN 320)
  • 3U-Series: 3U-Series 4-in-1 (ARO 310, Industrial, Truflate and CEJN410)
  • Parker UC-Series, Hansen Auto-Flo 23 and Coilhose Series UC
Construction:
  • Machined components are manufactured using solid bar stock.
  • Stainless steel springs. Carbon steel balls and retaining rings.
  • Valve components are machined from solid brass bar stock.
  • Nitrile (Nitrile Rubber) seals are standard. Providing a temperature range of -40°F to 250°F (-40°C to 121°C).
Safety Notes:
  • 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.
  • Note: Many competitive Universal couplings are unable to match the performance capabilities of the Dixon U-Series. Although the universal coupler permits multiple series nipples to mate with one coupler, it is recommended to match like series couplers and nipples. When using a universal coupler, the lower performance rating between the coupler and the nipple must take precedence.
  • Dry Air: Some pneumatic applications require the pressurized air to be 'dried' to ensure proper operation of equipment and/or application of product (ie. Auto body shops). It is best to match like series couplers and nipples in these applications. If it is necessary to use a Universal coupler, lube the seal and valve area regularly to ensure reliable service.
