ABSTRACT:
This invention relates to fluid filter units comprising a canister having a filter element permanently retained in the canister by an end plate. The end plate is attached to the canister by a closing ring which is joined to the end plate and which forms a seam joint with the mouth of the canister. An annular seal is provided at the junction of fluid leakage paths past the end plate to the inner and outer peripheries of the closing ring so that the seal closes both leakage paths.
Such filter units are particularly suitable for the lubrication systems of internal combustion engines.
