Fuel Filter Cartridge PF7782

The Baldwin Filters PF7782 is a cartridge-style fuel filter designed to separate water and contaminants from fuel systems. It serves automotive and heavy-equipment operators who need reliable filtration during routine maintenance or repair work.

Filter Design with Relief Valve

This element combines a fuel/water separator cartridge with an integrated relief valve to manage pressure differentials. The thread size is not applicable, so installation depends on the specific housing or mounting arrangement used in the application.

Dimensions and Included Seals

The filter measures 7 1/32 inches in height and length with a 3 27/32 inch outside diameter and a 21/32 inch inside diameter. Three O-rings and an attached grommet are supplied for sealing. It does not suit systems that require a threaded base or a different centre-bore diameter.

Questions about this item

What does the 7-1/32 inch height mean for installation space?

The cartridge stands 7-1/32 inches tall, so the filter housing must provide at least that much vertical clearance plus room to remove the element during service.

How does the thread size "Not Applicable" affect mounting?

With no threaded connection, this cartridge relies on the housing's internal seat and the three included O-rings plus the attached grommet to seal and stay in place.

What clearance is needed for the 3-27/32 inch outside diameter?

The housing bore must accommodate a 3-27/32 inch outside diameter, and the 21/32 inch inside diameter fits over the center post or standpipe supplied by the filter head.
