Morphology

piston + ring

The noun–noun compound is transparently built from 'piston' + 'ring' and a learner who knows both words can infer it is a circular part associated with a piston (a ring fitted to or around the piston). While the precise technical function (sealing gases and preventing oil leakage) is specialised knowledge, the basic referent and relation are directly derivable and follow common compounding patterns across languages.

Etymology

Piston ring is a metal ring that fits into a small groove on the piston inside an engine and presses against the engine wall to 'seal' the gap and stop gas and oil leaking out. That's why a worn piston ring lets gas and oil escape and causes engine problems.
