ABSTRACT:
Spin on disposable filters are useful in removing contaminants from the fluid of fluid systems. Preventing axial elongation of the filter due to fluid pressure therein requires the use of thicker elements, thereby increasing the manufacturing cost. The subject twist or disposable filter includes a twist-lock connector device which captures a portion of a housing between interconnected members of the twist-lock connector device. The twist-lock connector device is adapted for axial sealing engagement with a mounting device and minimizes the area of imbalance, thereby minimizing the forces tending to cause axial elongation of the filter. This permits the use of less expensive materials therein and simplifies the manufacturing procedure.
