Product Description
The m673 is a 14 mm copper spark plug gasket conforming to AN4027-2/MS17840-2 specifications. This gasket creates a gas-tight seal between the aviation spark plug and cylinder head while managing heat transfer from combustion. Installed on piston engines in general aviation and light aircraft, it prevents fuel and oil leakage at the plug interface.
Replace the gasket during spark plug service and torque the plug according to engine maintenance manual specifications. Copper construction provides reliable sealing across engine operating temperatures.
Please note: Product descriptions are provided for informational purposes. Always refer to your aircraft's Illustrated Parts Catalog (IPC) to verify part compatibility and specifications.
