Hydraulic Filter Element 9 in

The Baldwin Filters PT90-10 is a hydraulic cartridge filter element designed for equipment maintenance. It fits Allis Chalmers, Caterpillar, Fiat-Allis and Komatsu machinery using the PT90-10 or PT90-MPG part references. The reinforced centertube adds structural strength during operation.

Upgrade From Worn Cartridges

This element replaces a used hydraulic filter cartridge that has reached its service limit. The jump is worth it when the old element shows pressure drop, contamination buildup or has exceeded the recommended change interval. A fresh cartridge restores proper flow and protects downstream components.

45 Micron Rating and 9 Inch Height

The 45 micron rating captures particles that would otherwise circulate in the hydraulic system. The 9 inch height and 5 1/8 inch outside diameter provide the filtering surface area specified for the listed equipment. It handles the flow demands of those machines until the element loads with contaminants and requires replacement.
