Our porous stainless steel tubes are engineered for automotive particulate filter applications, providing durable, high-efficiency filtration in extreme conditions. Manufactured using 316L or 310S sintered stainless steel, these tubes are ideal for diesel and gasoline particulate filters (DPF/GPF), onboard fuel vapor filtration, and exhaust after-treatment systems.

With a uniform pore structure, high mechanical strength, and resistance to corrosion and heat, these porous tubes ensure long service life, minimal pressure drop, and superior filtration performance in harsh automotive environments.

Key Features & Advantages

High Filtration Efficiency

Precisely controlled pore sizes (0.5 – 30 μm) enable effective capture of fine particulates, soot, and metal debris from exhaust gases, improving engine performance and reducing emissions.

Extreme Temperature & Corrosion Resistance

Made from sintered 316L or 310S stainless steel, these tubes withstand continuous temperatures up to 800°C and resist corrosion from acidic exhaust gases and fuel residues.

Structural Integrity Under Pressure

Designed to maintain dimensional stability and mechanical strength even under rapid pressure and thermal cycling typical in automotive exhaust systems.

Compact & Space-Saving

The tubular design allows for compact integration in exhaust systems or fuel filtration modules without compromising filtration area or efficiency.

Reusable & Regenerable

Sintered porous tubes can be cleaned via backflushing or thermal regeneration, offering a longer service life and reduced replacement frequency compared to traditional ceramic or paper filters.
