Characteristics
Piston Cups are normally employed in moderate pressure cylinders up to 1500
P.S.I. A primary advantage is the ability to accommodate broad cylinder
diameter tolerances. Piston Cups have knife trimmed sealing lips to eliminate
all molding flash and to provide maximum sealing performance at low pressure.
In order to establish proper sealing interference on the piston cups, the piston
should be machined to the "L" dimension .
