Carbon commutators are a relatively new product used in automotive fuel pumps which also have great potential for use in other applications. Oriental Commutator Company provides customers with a variety of designs and industry leading technical support. Our carbon commutators offer these advantages:

• Resistance to aggressive fuels which attack conventional copper commutators
• Reduced draw on vehicle's electrical system
• Reduced radio frequency interference (EMI)
• Possible to produce a vehicle and ship it globally without concern of fuel pump failure due to corrosive fuels
