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 oilis not being pumped through the filter it can quickly drained using an air chuck forfilling 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 SeeThrough top allows the user tovisually inspect particles andcontaminants that were filtered out of the system without draining or leaking any fluid, unbolting or loosening any fasteners or fittings and with out any lossof oil. Seeing these filtered particles will help determine if they are from normal use orfrom bearings and other components excessively wearingin the engine or machinery supplying the Filter Assembly.

• When using 50 weight or lighter oila 60 micron element is recommended. When using 60 weight or heavier oil A 115 micron element is recommended.
• Filters have 2 Inlet and 1 Outlet Openings that are threaded for#12 O-Ring Boss - 1-1/16-12 TPI fittings. The Inlet and Outlet Ports are machined to 5/8" diameter and will not restrict the flow when using a#12 line.
• Not recommended for all Aluminium Hemi combinations with external oil pumps
