Baldwin PT491-10 Hydraulic Filter Element

This cartridge-type hydraulic filter element measures 18 inches in length and height with a 6 inch outside diameter. It features a 9.8 micron rating, reinforced centertube and attached end seals for secure installation. The element is designed for hydraulic systems on Michigan, Austin, Western, Clark, V.M.E. and Volvo equipment.

9.8 Micron Rating and Nominal Dimensions

The 9.8 micron rating defines the practical filtration limit for this element. Particles smaller than this threshold will pass through the media. The 18 inch height and 6 inch diameter set the physical envelope that the host filter housing must accommodate. Thread size is not applicable for this cartridge design.

Capacity and Service Headroom

The reinforced centertube and attached end seals provide structural headroom against pressure spikes and flow surges in compatible hydraulic circuits. The element handles standard hydraulic fluid volumes for the listed equipment brands. It does not suit systems requiring finer micron ratings, different cartridge dimensions or threaded mounting interfaces.
