What is the purpose of the top compression ring?

The top compression ring is the primary seal in the piston ring set. Its main job is to create a tight seal between the piston and the cylinder wall, preventing combustion gases from escaping into the crankcase and helping to transfer heat from the piston to the cylinder wall.

Are these rings sold individually or as a set?

This product is a set of top compression rings. For a complete engine rebuild, you will typically need a full set of piston rings for all cylinders, which may include oil control rings and second compression rings.

What does the '.010' in the part number mean?

The '.010' in the part number 42214CP.010 indicates that these rings are 0.010 inches undersize. This is common for engine rebuilds where cylinder bores may have been honed to a specific oversize to ensure a proper fit with the pistons and rings.
