Baldwin PT8959-MPG Hydraulic Filter

The Baldwin PT8959-MPG is a cartridge-style hydraulic filter element designed for fluid power systems. It uses wire mesh supported maximum performance glass media to capture contaminants. The unit includes an O-ring for sealing and has no thread size. It suits maintenance technicians and equipment operators needing reliable hydraulic filtration.

Cartridge Element Installation

Installation requires removing the used cartridge and seating this element into the existing filter housing. The included O-ring must be lubricated and seated evenly to prevent bypass leakage. A common issue occurs when the old seal remains in the housing groove, causing a double seal that fails under pressure. Correct alignment avoids this problem.

Filtration Capacity and Limits

The glass media provides high dirt-holding capacity for extended service intervals in typical hydraulic circuits. It handles standard flow rates for the housing it fits. The element reaches its limit when the pressure differential across the media triggers the system bypass indicator. At that point, flow continues unfiltered until the cartridge is replaced.
