Sintered Porous Metal Filter Tube & Cartridge is used for filtering gases, steam, solvents and process liquids through rigid sintered stainless powder tubes that can be back-flushed and reused for years. ASTM E128 is the reference cited for it on drawings, datasheets and purchase orders.
What ASTM E128 Means for Sintered Porous Metal Filter Tube & Cartridge
The dimensions in the table below are supplied to suit ASTM E128. Where the standard sets requirements for the finished appliance, device or system, compliance testing of that assembly stays with its manufacturer; we supply the metal mesh part to the drawing and can provide material certificates and dimensional reports with the shipment.

Specifying Sintered Porous Metal Filter Tube & Cartridge Beyond the Standard
- Micron rating: From 0.5 to 100 µm; specify liquid or gas rating, which differ for the same element.
- Dimensions & wall: OD, length and wall thickness set flow and strength.
- End fittings: Welded caps, NPT, DOE, 222/226 O-ring or flanged ends.
When Sintered Porous Metal Filter Tube & Cartridge Is Not the Right Choice
Not economical for high-volume, low-value water filtration where disposable cartridges are cheaper.
