A fluid system pressure indicator is adapted for use in fluid systems having a filter element. The fluid system force indicator includes a housing partitioned to be exposed to the fluid system to provide transmission of a mechanical force between these partitioned environments to indicate the fluid pressure. This exterior shape change is such that it can be identified through tactile means not requiring visual identification.

Filter change indicator

A modular base for a filter assembly includes a header portion defining a cavity for receiving a filter cartridge and a communication module defining fluid pathways to and from the base. Brackets extend from the header portion and include slots. Yokes extend from the communication module to complement the slots. The brackets and received yokes together define pathways into which generally tubular compression limiters are inserted. The compression limiters serve dual functions by retaining the communication module to the header portion and reinforcing the brackets. A sealing grommet disposed between the header portion and communication module enhances the sealed integrity of the base.
