The Pingel adapter nuts are for use in adapting petcock fuel valves to some older Japanese motorcycles.  The A2003C adapter nut threads onto the male bung of the tank and allows the fuel valve to thread into the adapter nut.  The adapter nut fits to 18mm fuel tank bungs and fits any 1/4" NPT fuel petcock valve. 

Some but not all of the models this will fit are as follows:

• Honda CB400 (1975)
• Honda CB550 (1975)
• Honda CB900C (SOME MODELS, Please check fitting diameter)
  
• Honda CB1100F (1983)
• Honda CBX (1982) 6111-AH
• Honda VF750S Sabre
  

We offer ALL Pingel items with fast delivery and everyday low prices.  Please inquire if you do not see your valve or model listed.
