Abstract
A filter assembly is provided having an oversized generally cylindrical housing defining a housing edge. A filtering element is disposed in the housing for filtering the fluid. A generally circular unitary tapping plate is also provided having a fluid inlet port, a fluid outlet port, and mounting means for removably mounting the filter assembly to the fluid circulation system. The unitary tapping plate further having a generally U-shaped portion defining a seal retaining groove and a wing portion extending radially outwardly from said U-shaped portion. The edge of the housing surrounds the tapping plate and is folded inwardly over the wing portion of the tapping plate such that a free end of the housing edge generally terminates in the seal retaining groove. The filter assembly also includes an external seal having a generally rectangular cross-section that is retained in the seal retaining groove. The wing portion of the tapping plate enables the outer diameter of the housing and the filtration area of the filtering element to be increased, without increasing the diameter of the external seal.
