Advanced Efficiency Hydraulic/Transmission Filter

Smart Cat equipment owners protect their machinery – and livelihood – when they choose genuine Cat filtration products.

Cat Advanced Efficiency Hydraulic and Transmission Filters provide increased contamination control without giving up superior dirt-holding. Using improved filter media, our filters offer higher efficiency, improved capacity and lower pressure drop characteristics.

Pleat spacing is rigidly maintained by acrylic beading that prevents bunching and provides maximum filtration surface area throughout the life of the filter. In addition, the integrated seal ensures a separation between the clean and dirty sides of the element.

While it may seem as though will-fit filters are suitable for your machinery, no other company knows your equipment like we do. Because Cat maintenance products are designed and produced by the same company that manufactures your machinery, you can count on our filter elements to deliver superior fit and performance every time. Switch to Cat Filters today by contacting your local Caterpillar dealer or search using your will-fit part number at

  • Cat Advanced Efficiency Hydraulic and Transmission Filters offer an increased level of protection offering the following benefits:
