The UH319 Series High-Pressure Filters are engineered for heavy-duty hydraulic applications requiring maximum reliability. Designed as a high-performance alternative to the Pall Ultipleat SRT series, our UH319 filters provide superior protection for sensitive components like servo valves and high-pressure pumps. With a fatigue pressure rating of up to 420 bar, these filters are the industry standard for steel mills, injection molding, and mobile equipment.

Static Reduction Technology (SRT): Filter media prevents electrostatic discharge, reducing oil oxidation and varnish buildup.
High Beta Efficiency (
βx(c)≥1000beta sub x open paren c close paren end-sub is greater than or equal to 1000
𝛽𝑥(𝑐)≥1000): Provides ultra-clean fluid to extend the life of your hydraulic system by up to 10x.
Stress-Resistant Pleat Design: The patented laid-over pleat geometry ensures stable filtration even under severe pressure surges and cold starts.
Direct Interchangeability: 100% compatible with Pall original parts (UH319F, UH319S, UH319C).
