A filter apparatus is described that has a torque limiting device, which may be a clutch mechanism, and which provides a protective function for a filter, so as to protect a filter from being over tightened and to thereby prevent damage to filter components. The clutch mechanism can also eliminate or reduce the need for torque measurement of certain filter components. The clutch mechanism can be located on one of the fluid filter, a filter head which engages the fluid filter, or a combination of both the fluid filter and the filter head.

Filter apparatus with torque limiting mechanism

A fluid filter device is described, where a flow attachment member provides a unique interface between the filtering element and a filter head. The fluid filter described herein generally provides a flow structure that is localized and sealed. The flow attachment member is configured to communicate fluid into and out of the fluid filter, and is configured to localize fluid flow both into and out of the fluid filter within a separating structure of the flow attachment member. The flow attachment member further includes a seal structure configured to substantially prevent or at least confine leakage to a localized area away from proximity of the edges of the housing. A composite filter head is described that has integrally molded inlet and outlet fittings.

Filter with localized flow attachment and filter head

A filter assembly where the filter cartridge is secured to the nutplate and a seal is provided between the filter cartridge and the nutplate. The sealing relationship between the filter cartridge and the nutplate is maintained during use of the filter assembly without using a spring engaged with the filter cartridge that biases the filter cartridge into engagement with the nutplate.
