4″ Dry-Sump Oil Filter Assembly

4″ Dry-Sump See Through Filter Assembly with #16 Ports and 115 Micron Element are for running all weight oils up to 70 weight. Designed to be mounted between the Dry-sump oil pump and the oil tank on a #16 scavenge line. Also for applications where the oil tank has a flat bottom and running 50 weight oil. Flat bottom unlike tapered bottom tanks particles will settle to the bottom and may not be sucked through the pressure side of the oil pump for inspection. Tapered bottom tanks can run the See Through filters with or without a screw-on disposable filter on the pressure side between the Dry-sump oil pump and the engine inlet oil port.

See Through Oil Filters can be used for many applications including Racing, Marine, Automotive, Farm, and for Industrial Hydraulic Systems. These Patented Oil Filter Assemblies allow the user to visually see oil pumping through the filter, which helps to determine the condition of the oil. When oil is not being pumped through the filter it can quickly drained using an air chuck for filling tires and compressed air. A hand bicycle pump will also work. Apply a small shot of air to the air fitting on the side of the inlet opening. Oil will empty out of the assembly in seconds exposing the filter element and filtered particles, even when filtering non transparent fluids like dirty oil. The See Through top allows the user to visually inspect particles and contaminants that were filtered out of the system 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.
  • When using the Dry-Sump filter a 115 micron element is recommended.
  • Filters with #16 Ports have 2 Inlets and 1 Outlet openings. Inlet and Outlets are threaded for #16 O-Ring Boss – 1-5/16-12 TPI fittings. Port openings are machined to 7/8″ diameter and will not restrict fluid when using #16 lines.
