  • Parker 10 Series, Rectus 55KM and Tomco A2100/PT400
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. (temperature range of -40°F to 250°F (-40°C to 121°C))
  • Steel componentry is plated using ROHS Compliant Trivalent Chrome.
  • Steel sleeve and 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.
