Product identity
The Baldwin Filters PT9303-MPG is a cartridge-style hydraulic filter element built with wire-mesh supported Maximum Performance Glass media. It serves technicians and equipment owners who need a direct replacement element for compatible hydraulic systems. The unit ships new and includes an O-ring for sealing.
Sustained operation
The glass media is designed to maintain filtration efficiency over extended service intervals rather than only during initial flow. Wire mesh support resists collapse when pressure differentials rise during heavy use. The cartridge format allows the element to be swapped without replacing the entire housing.
Installation notes
Overall length is 12 15/16 in with an outside diameter of 3 9/16 in and an inside diameter of 1 23/32 in. Thread size is not applicable, so the element seats by compression against the supplied O-ring. Builders who need a spin-on canister or a different end-cap design cannot use this part.

Questions about this item
How much heat does the PT9303-MPG generate during continuous hydraulic operation?
The cartridge element has no moving parts and produces no measurable heat; system temperature depends on the pump and fluid, not the filter.
What housing or seal kit is required to install this Baldwin element?
It fits a compatible cartridge housing with a 1 23/32 in. bore and includes the necessary O-ring for sealing.
Will this filter thread into an older Baldwin housing that uses a screw-on canister?
No — the PT9303-MPG is a threadless cartridge design, so it only works in housings built for drop-in elements with an O-ring seal.
