This filter was designed and recommend for tractor pulling and other motor sports ran on dirt. This filter uses a very coarse 380 micron element which allows diesel soot and microscopic particles to flow into the disposable filter. The oil first flows through the See Through Filter which the filter element traps the larger particles that can be viewed and inspected while the soot and microscopic particles flow into the disposable filter and are filtered out of the oil. The filtered oil then flows out of the filter assembly through the outlet opening. This dual stage filter will extend the life and flow of the disposable filter and still allow visual inspection of filtered particles without draining or leaking any fluid, unbolting or loosening any fasteners or fittings and with out any loss of oil. Seeing these filtered particles will help determine if they are from normal use or from bearings and other components excessively wearing in the engine or machinery supplying the Filter Assembly.
  • Filters have 2 Inlet and 2 Outlet Openings that are threaded for #16 O-Ring Boss – 1-5/16-12 TPI fittings. All 4 ports can be used. #16 fittings can go in and out on the same side of the filter.
