Filter Diameter - This is the overall diameter of the filter. Always use the largest diameter practical to insure maximum filtration.
Filter Length - This dimension is the length of the filter body only, it does not include the flange length. Always use the longest filter practical for maximum filtration.
Flange Angle and/or Length - If no angle is listed in the specifications table, the flange is straight.

Flange Type - The location of the flange in relation to the O.D. of the filter is sometimes offset to one edge of the filter for more clearance in an application.
