Please note:
This range of seals is for the LX range of pumps 2008 onwards.
If your pump is prior to this PLEASE COMPARE PHOTOS TO SEE IF THE SEAL IS LIKE THAT REQUIRED. The DH1.0 current seal was widely used in other LX pumps prior to 2008. This may be the seal you need if your pump is older than 2008 (we have seen them used in TDA150, TDA200, EA350).
