Hydraulic Filter Element
The Baldwin Filters PT139-10 is a cartridge-style hydraulic filter element designed for pressure-type systems. It features a 5 micron rating and exposed pleats to capture contaminants in hydraulic fluid. An attached gasket is included for sealing. The element fits Marvel TB578366 housings and Caterpillar lift trucks.
Sustained Filtration Performance
Under continuous pressure the element maintains its rated 5 micron filtration across the full pleated surface. The cartridge construction supports steady flow without bypass during normal operating cycles. The attached gasket remains seated under system pressure to prevent unfiltered fluid from passing the seal.
Direct Housing Replacement
This element replaces a spent cartridge inside a Marvel TB578366 housing without changing the head or plumbing. The upgrade is worth it when the previous element has reached its service interval or shows a rising pressure differential. It is not for buyers who need a complete filter assembly with a new head or a different thread configuration.

Questions about this item
How much hydraulic pressure and heat can the 5-micron cartridge handle during continuous operation?
The cartridge is rated for 5-micron filtration in pressure-type hydraulic systems and includes an attached gasket to maintain seal integrity under normal operating temperatures.
Which housing must I already have for the PT139-10 element to fit and seal correctly?
It is designed for the Marvel TB578366 housing used on Caterpillar lift trucks; the element has a 2-1/4 in inside diameter, 4-1/2 in outside diameter and no threads.
Will this filter work if I keep my existing Caterpillar lift-truck hydraulic circuit unchanged?
Yes — the element matches the Marvel TB578366 housing specification for Caterpillar lift trucks, so it installs directly without modifying the circuit.
