The 2695 Injector Seal Pack uses 700002760. The old number for this seal was WAT033276. When ordering, use part number 700002760. Alternatively you might want to use the Seal Pack Rebuild Kit w/Needle (Part number WAT271019)
This is not to be confused with the similar looking seals (Part Number 700005019) in the high pressure valves of the 2695 (HPMV, Valve 1 and 2).
