There is an o-ring (2-014 I believe) that seals the plastic parts to the metal parts. It is a sandwich of two metal parts that screw together capturing the plastic piston face that needs some type of seal. I have successfully disassembled and replaced the o-ring but it is not a SP procedure. The two metal parts are screwed together and you should be able to see a dot of red Loctite in a hole on the piston just above the shaft that has to be clean out to unscrew the two metal pieces. There is a flat on the one surface that can be gripped with a wrench and I believe I used an easy out through the top hole to grip the other piece.
The O-ring is visible in some cut-away drawings of the composite piston and left out of others. I guess it is like a family secret SP does not want to tell you about.
