The FA1 142-956 Exhaust Sintered Sealing Ring is designed for professional mechanics and automotive DIY enthusiasts who need a robust, high-performance gasket for exhaust system maintenance. Its primary benefit is a high-precision, heat-resistant seal that prevents exhaust leaks and improves overall system longevity, though users should ensure their specific vehicle's exhaust flange dimensions perfectly match the 56mm x 69mm x 19.5mm specification before installation.

No, this is a dry-fit sintered component designed to seal via mechanical pressure.
Verify your vehicle's exhaust flange diameter matches 56mm inner and 69mm outer, and check the FA1 142-956 compatibility list for your specific MERCEDES-BENZ or CHRYSLER model.
It is highly recommended to replace the sealing ring every time the exhaust connection is opened, as the material compresses to form the seal and may not recover its shape.
The ring is made from sintered metal, chosen for its ability to handle high pressure and thermal cycling.
19.5mm refers to the thickness (or height) of the ring when measured flat.
Verify that the exhaust pipe flange bolts are tightened evenly to the manufacturer's torque specifications to ensure uniform pressure on the ring.
Double-check that the pipe inner diameter is 56mm and outer diameter is 69mm; ensure no carbon buildup is preventing the ring from seating fully.
Before installation, ensure the mating surfaces of the exhaust pipe are free of rust, debris, and remnants of the old gasket. Use a wire brush to clean the flange interface to ensure a smooth seat for the new ring. This component does not require liquid gasket sealants. For compatibility, always cross-reference your specific vehicle's VIN or exhaust system diagram with the FA1 142-956 part number. Periodic inspection is recommended during oil changes to ensure the flange bolts remain tight and the seal shows no signs of carbon tracking.
