ABSTRACT:
Spin on disposable filters are useful in removing contaminates 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 on disposable filter includes a twist-lock connector device which captures a portion of a housing between cooperating members of the twist-lock connector device. The area of imbalance caused by seal placement is greatly reduced by the twist-lock connector device, 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.
