353122E613 Hyundai / KIA COMBUSTION SEAL RING, Price: 10.97$, Weight: 0.005kg

Engine Combustion Seal Ring (Heat & Pressure Gasket)

This precision seal ring is a small but critical engine part that keeps combustion pressure exactly where it belongs—inside the cylinder chamber. It’s needed whenever the engine is assembled or serviced around the injector/plug seat or combustion interface, because even a tiny leak can reduce power and raise exhaust temps.

How It Works ⚙️

The ring crushes slightly during tightening to create a gas-tight barrier. This “crush seal” blocks blow-by, stabilizes compression, and protects nearby components from hot gases and soot. Built to handle extreme heat cycles, it maintains sealing even when the engine expands and contracts.

What If It’s Worn or Broken ❌

A damaged seal ring can cause compression loss, rough idle, ticking/puffing sounds, fuel smell, soot around the seat area, higher fuel use, and misfire faults. Long-term driving may burn the sealing surface, overheat parts, and lead to costly head or injector seat repairs.

Technician Tip ️

Always replace the seal during reassembly, clean the seat, and torque to spec—reusing an old crush ring is a common source of repeat leaks.
