A seal ring for a spark plug shaft is a sealing component installed around the spark plug tube or shaft in the cylinder head. Its function is to prevent oil and contaminants from entering the spark plug well, ensuring proper ignition performance.
Key specifications include inner and outer diameter, thickness, material (such as heat- and oil-resistant rubber or silicone), temperature resistance, and compatibility with the engine. It must withstand high temperatures and exposure to oil.
Replacement is necessary when the seal is worn, hardened, or leaking. Common symptoms include oil in the spark plug wells, misfires, or reduced engine performance.
