The ss316 sintered powder filter element is a high-performance miniature sintered metal filter element manufactured from premium 316L stainless steel powder through advanced high-temperature vacuum sintering technology. This filter element delivers exceptional filtration performance in space-constrained industrial applications where conventional filter media would be impractical or fail.
Engineered from 316L low-carbon stainless steel — this filter element is designed to withstand the most aggressive operating conditions. The powder sintering process creates a three-dimensional network of interconnected pores with uniform pore distribution and no blind pores, enabling depth filtration where particles are captured not just on the surface but throughout the filter’s entire thickness.

This sintered filter is suitable for precision filtration in the following industries:
This sintered filter is manufactured by Huahang Filter, leveraging expertise in powder sintering technology and metallurgy. We focus on producing reliable, application-specific metal filters. Our controlled sintering process ensures consistent pore structure and performance in every batch. We provide technical support for material selection and can offer custom versions of this platform element with different end fittings, lengths, or surface treatments to meet unique system integration needs.
Controlled Sintering for Consistent Porosity: Our sintering process is finely tuned to create a uniform porous matrix, providing a reliable and predictable absolute filtration rating (e.g., 2, 5, 10, 20, 40 microns) in this small form factor.
Precision Thread Machining: The G¾ threads are machined to exacting standards, ensuring a perfect seal with standard fittings and preventing cross-threading or leakage in critical fluid paths.
High Material Purity & Integrity: We use high-grade 304 or 316L stainless steel powder, resulting in a filter with excellent corrosion resistance and structural integrity suitable for demanding analytical or process applications.
Durability and Cleanability: Despite its small size, the monolithic sintered structure is robust and can be backflushed or ultrasonically cleaned numerous times, offering long-term service life and value.
