What this filter is
This Baldwin Filters PT9477 is a hydraulic cartridge element built with stainless steel mesh. It suits equipment owners who need a replacement filter for hydraulic systems that accept this specific cartridge design and dimensions.
Practical limits of the cartridge
The element measures 3-15/16 inches in both height and length with an outside diameter of 1-3/4 inches. It has no thread size and relies on the housing for sealing, so it only fits applications that match these exact physical constraints.
Installation and common issues
An attached gasket is included to simplify the seal during installation. The main risk is fitting the cartridge into a housing with mismatched dimensions, which will prevent a proper seal and allow unfiltered fluid to bypass the element.

Questions about this item
Which Baldwin Filters PT9477 hydraulic filter element size should I choose?
The PT9477 is a single cartridge with a 3-15/16 in height, 3-15/16 in length and 1 3/4 in outside diameter, so there is only one version to select.
What does the 3-15/16 in dimension mean when the filter is installed in a hydraulic system?
That measurement gives the cartridge height and length, so it determines the housing space needed and the flow path length through the stainless steel mesh element.
What connection standard does the PT9477 use and what does it limit?
The element has no thread size — it is a cartridge that seats inside a compatible housing, so the housing dictates the port standard and pressure rating.
