TWIN RING Piston Ring This type of cut CPI filled PTFE piston ring is comprised of two rings dowelled together to prevent gap alignment. Piston ring construction . Turn the piston ring joints of the installation-ready piston so that the piston ring joints are turned roughly 120° towards each other. Skirt diameter is smaller than the recommended bore size (see sizing on box). The ends of the spiral expander must always be opposite the ring joint.
