SO-HPP-PT20 is the O-ring in the deepest groove of the 20% Clark Pump piston. HP-CYL-PTS20, the separate outer piston seal, fits over it.
The piston also has two HP-CYL-PTB20 bushings in its other grooves. One PT20 O-ring is used per illustrated piston. This is a cylinder-piston seal, distinct from the rod seals housed in the center block.
