HPLC Piston Seal Insertion
Tool
Top: Using the tool to remove the old piston
seal from the housing.
Insert the threaded end of the tool into the exposed
seal and turn in a clockwise direction until the tool
grips the seal. Pull it straight out of the housing.
Bottom: Using the tool to insert a new seal.
Insert the smooth end of the tool into the new piston
seal. Firmly push the seal straight into the pump
housing. The stepped tip of the tool ensures a pre-
cise depth fit into the pump housing. This prevents
expansion/deformation of the seal on insertion and
helps maximize the life of the seal.
