Overview
HP-CYL-PT20 is the 20% Clark Pump piston body. The factory guide describes the 20% piston as Delrin with replaceable sealing parts.
Each illustrated piston uses SO-HPP-PT20 in the deepest groove, HP-CYL-PTS20 over that O-ring, and two HP-CYL-PTB20 bushings in the remaining grooves. These are separate part numbers; KIT-HP-20PTA is the assembly-level listing shown in the parts guide.
