Suit TD42T Engines.
This is the gasket that goes onto the front of the compressor housing of the turbo.
Whenever the pipe on the front of the turbo has been disconnected, it is a good idea to replace this gasket to ensure a good seal that doesnt leak, you dont want dust bypassing the air cleaner and going straight into the turbo / engine.
We also have a large range of gaskets and seals for the TD42 engine, and available in our online store.
