Introduction
Contamination in hydraulic oil can accelerate component wear, obstruct control passages, damage pumps and valves, and reduce the operational stability of industrial machinery.
The Taisei Kogyo P-UM-03-10U Hydraulic Filter Element uses pleated paper media with a 10 μm filtration rating to support oil cleanliness in hydraulic systems equipped with compatible Taisei Kogyo UM line-filter housings.

Filtration for Hydraulic Equipment Protection
The UM Series is installed directly in hydraulic piping to capture solid contaminants circulating through the system.
The P-UM-03-10U element provides the filtration surface required to protect hydraulic components while supporting oil circulation through the filter housing. Its pleated construction increases the available filtration area within a compact cylindrical configuration.
The UM housing uses an upper-extraction design, helping simplify element replacement during scheduled maintenance.
Technical Overview
Parameter | Confirmed Specification |
Manufacturer | Taisei Kogyo Co., Ltd. |
Product Type | Replacement hydraulic filter element |
Individual Model Code | P-UM-03-10U |
Compatible Filter Series | UM Series |
Filter Classification | Medium-pressure inline filter |
Filter Media | Paper |
Filtration Code | 10U |
Filtration Rating | 10 μm |
Standard Fluid | General mineral oil |
Associated Housing Size Code | 03 |

The 7 MPa rating applies to the compatible UM filter housing. The element’s suitability must be confirmed according to the complete housing model, fluid, temperature, flow rate, differential pressure, and maintenance conditions.

Industrial Applications: Taisei Kogyo P-UM-03-10U filter element
The P-UM-03-10U filter element may be used in compatible filtration systems for:
Hydraulic power units
Industrial machinery
Machine tools
Hydraulic presses
Manufacturing equipment
Lubrication and oil-circulation systems
Power-generation auxiliary equipment
Marine and heavy-equipment hydraulic systems
Exact Replacement Identification
A filter element should not be selected only by its external dimensions or apparent physical similarity.
Technical verification should confirm:
Complete filter-element code
Filter-housing manufacturer and model
Filtration rating and media type
Hydraulic fluid and viscosity
Operating temperature
System flow rate
Operating pressure
Required contamination-control level
Element seals and compatibility
Required quantity
The 10U code identifies a 10 μm paper element. Other Taisei Kogyo filtration codes may use different paper, fiber, wire-gauze, or notch-wire media and should not be treated as automatically interchangeable.
