FC216022003 is an OEM Rolair piston, connecting rod and ring set designed for Rolair PMP11MK238FI portable air compressors. The kit includes a complete piston/connecting-rod assembly with the ring set and replaces older Rolair part numbers such as 216022002F and FC416022004, making it a direct compatibility option within the PMP11MK238FI family. Use this replacement to restore compression and mechanical integrity when the piston, rod, or rings wear or fail in compatible Rolair units.
