Product details
Filtration grades
Media grades include 5, 10, 20, 50, 75 and 100 µm; fine 1–2 µm configurations use fine or sintered mesh. Media grade and measured retention are specified separately in the filtration requirements.
Dimensions
Outside diameters include 60 and 80 mm, including an 80 mm OD × 40 mm ID configuration. Nominal lengths are 5, 10, 20, 30 and 40 in, with custom finished dimensions.
Materials and connections
304, 316 and 316L constructions combine DOE, 222, 226 or threaded ends with silicone, EPDM or FKM seals. Core, joints and seals are sized for operating temperature, differential pressure and the specified cleaning cycle.
Integration with the filter assembly
The pleated assembly separates the retaining mesh, drainage mesh, inner perforated core, outer guard and end caps. Woven mesh, sintered mesh and sintered metal fiber felt are distinct media constructions: the drawing identifies the actual pleated material. Pleat height and count determine the developed media area, while pleat spacing leaves channels between neighbouring folds. The longitudinal closing joint and both end-cap joints close the bypass path. Outside-in flow loads the inner core; reverse cleaning also loads the outer restraint.
DOE, SOE and locating ends
DOE means double open end; SOE means single open end. A 222 or 226 adapter specifies an O-ring sealing and retention interface at the open end of an SOE cartridge. A fin locates the opposite closed end in the housing support. Record both ends on the replacement drawing, together with overall length, seal diameter, insertion depth and any locking lugs.

Applications
Process-liquid cartridges
Pleated stainless mesh elements for liquid filtration where a defined flow path and a cleanable metal medium are useful. Select grade and support against the actual liquid and pressure drop.
Gas and hot-process service
304, 316 and 316L constructions combine DOE, 222, 226 or threaded ends with silicone, EPDM or FKM seals. Core, joints and seals are sized for operating temperature, differential pressure and the specified cleaning cycle.
Drawing-based replacement elements
Custom replacement cartridges reproduce the housing dimensions, sealing faces and end connections.
Selection guide
Include these details when discussing your requirements.
- Housing drawing and fit
- Provide OD, ID or core bore, overall length, end views, sealing diameter and insertion depth. A used sample is helpful, but critical dimensions must be measured.
- Filtration duty
- State fluid or gas, target particle size, flow rate, viscosity where relevant, and whether the grade is nominal, absolute or defined by a specific retention test.
- Media and construction
- Media grades include 5, 10, 20, 50, 75 and 100 µm; fine 1–2 µm configurations use fine or sintered mesh. Media grade and measured retention are specified separately in the filtration requirements.
- Pressure, temperature and cleaning
- List normal and upset temperature, initial and maximum differential pressure, flow direction, cleaning chemicals and any backwash cycle.
- End connection and seal
- Send end-cap drawings or photos and state DOE, 222/226 or threaded interface requirements, seal material and sealing-seat dimensions.
- Order and acceptance
- The inspection record identifies the material, finished dimensions, joining surfaces and sealing interfaces. Measurements follow the installed geometry and the stated test conditions.
Frequently asked questions
What changes when a cartridge is pleated?
Pleats increase media area within the cartridge envelope. Keep sufficient space between pleats for flow and cleaning; the housing dimensions, core and outer guard determine how much area can be used.
How should I specify a 1 or 2 µm element?
Select the fine-mesh or sintered-mesh construction and specify retention efficiency, test fluid and operating conditions for that grade. Include clean pressure drop and the allowable terminal differential pressure in the cartridge specification.
