Product Data:

Series:
  • D Series
Shape:

Straight

Ends Configuration:
  • 3/8in Female ISO-6150 Series B Industrial Pneumatic QD Interchange
  • 1/2in Male NPTF
Compatibility & Interchange:
  • Foster 3, 4, 5 and 6 Series
  • Parker 30 - Series Automatic Interchange
  • Hansen 3000, 4000, 5000 and 6000
Construction:
  • Machined components are manufactured using solid bar stock.
  • Stainless steel balls, retaining rings and springs maximize corrosion resistance and extend service life.
  • Nitrile (Nitrile Rubber) seals are standard.
  • Steel componentry is plated using ROHS Compliant Trivalent Chrome.
  • Steel tubular valve.
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.
