Part number for FDM check valve is obsolete or incorrect - WKB1733

Article number: 1733

SYMPTOMS

  • Thar p/n 01377-1  = Check Valve, 3/8"Dia, 10k PSI, 1/8 Ball
  • Thar p/n 01377  = Check Valve, 3/8"Dia, 10k PSI, Cartridge
  • Waters p/n 700006601  =  Check Valve, 3/8"Dia, 10k PSI, 1/8 Ball
  • Waters p/n 700006600  =  Check Valve, 3/8"Dia, 10k PSI, Cartridge
  • Waters p/n 700008840  =  Check Valve, 3/8" x 0.646", 10k psi

 

  • Thar p/n = 01377, taken from packaging; when entered into the ordering system, it brings up Waters p/n 700006600
  • p/n 700006600 are the check valves for the P-200A pump, not the FDM

 

  • Thar p/n 01377-1, when entered into the ordering system, brings up Waters p/n 700006601, noting the p/n is obsolete
  • Waters p/n 700006601, when entered into the ordering system, brings up Waters p/n 700008840
  • Waters p/n 700008840 was ordered and received; the part looks very different than Waters p/n 700006601

ENVIRONMENT

  • Waters/Thar FDM10
  • Waters/Thar FDM30
  • Fluid Delivery Module

CAUSE

The reason incorrect or obsolete part numbers are provided by the ordering system is unknown. Information in SAP may be incorrect.

FIX or WORKAROUND

  1. The correct check valve part number for the FDMs is 700008840  (Check Valve, 3/8" x 0.646", 10k psi).
