Description

This injector sleeve acts as a dry housing tube fitted into the cylinder head to separate the injector from the coolant passages in diesel engines. It ensures the injector remains on the correct axis and at a fixed depth while maintaining a vital seal between the combustion chamber and the water jacket. By conducting heat from the injector to the coolant, it also serves as a critical thermal bridge.

This component is designed for use in various Volvo engines, including the TD100, TD120, TD70, D10A, and D12A series. It is compatible with several Volvo models such as the F10, F12, F7, FL10, FL12, N10, N12, NL10, NL12, B10B, B10M, and B12. These heavy-duty parts are essential for maintaining compression and preventing coolant contamination in commercial engine systems.

When performing maintenance or injector service, technicians should inspect the sleeve for signs of thermal wear or erosion. It is highly recommended to renew the sleeve along with its sealing elements to prevent leaks. Ensure that all installation surfaces are clean to maintain a proper seat within the cylinder head.

Consult your authorized distributor to check the compatibility list.
