PP Pleated Filter Cartridges
70 mm, 83 mm, 130 mm outer diameter pleated cartridges in 5 to 70 inch lengths. Max 80℃, 4 bar at 21℃. Dimensional equivalent to common OEM series.
What The PP Pleated Does In Your Line
PP pleated filter cartridges are depth pleated cartridges with a single piece full length polypropylene media pack, an inner core, and an injection moulded outer cage. They are designed for outside-in flow to retain captured solids during change-out. Available in 70 mm, 83 mm, and 130 mm outer diameters and lengths from 5 inch to 70 inch, they are dimensional equivalents to common OEM series and fit into standard housings without adapters. The cartridges are made with polypropylene media and support, and are rated for up to 80℃ and 4 bar differential pressure at 21℃.

Why Buyers Pick This Element
- Single piece full length media pack eliminates joints and reduces leak risk
- Outside-in flow retains captured solids during change-out
- High surface area from pleated construction extends change-out intervals
- Available in multiple outer diameters and lengths to match existing housings
- Polypropylene construction resists common chemicals and water
- Dimensional equivalent to common OEM series so no housing change is needed
Buyers Who Specify This Cartridge
- Plant engineers replacing OEM depth pleated cartridges in existing filtration skids
- Procurement teams sourcing cost-effective replacements with short lead times
- Filtration distributors specifying drop-in equivalents for OEM part numbers
- System integrators designing new water treatment lines with standard cartridge fits
What It Fixes On The Line
- OEM cartridges have long lead times and high unit cost per replacement cycle
- Jointed media packs in older cartridges increase the risk of leaks and bypass
- Pleat collapse under differential pressure reduces effective filtration area
- Solids fall off the cartridge during change-out and contaminate downstream lines
- Lack of dimensional equivalents forces housing upgrades or system redesign
Construction Detail
- Single piece full length pleated media pack with no joints along the cartridge
- Polypropylene media, core, cage, and end caps for chemical resistance
- Outer cage injection moulded to maintain pleat geometry under pressure
- Outside-in flow path to retain captured solids during change-out
- Available in 70 mm, 83 mm, and 130 mm outer diameters and 5 to 70 inch lengths
- O-ring options include Silicone, EPDM, Buna-N, and Viton for different fluid compatibility
Materials Of Construction
- Polypropylene filtration media, thermally bonded without adhesives or surfactants
- Polypropylene inner core, injection moulded outer cage, and end caps
- Silicone O-rings for low extractable and wide temperature range service
- EPDM O-rings for general water and hot water applications
- Buna-N O-rings for hydrocarbon and general industrial water service
- Viton O-rings for aggressive chemicals and higher temperature duty

Sea water intake filtration ahead of cartridge or membrane stages
How This Cartridge Is Built
Media Preparation
Media extrusion and pleating to a fixed pleat pitch
Pack Forming
Vertical pleat pack forming to full cartridge length in one piece
Hardware Assembly
Core insertion and injection moulded cage assembly
End Cap Bonding
Thermal end cap bonding without adhesive
Configuration
O-ring and adapter fitting to the ordered configuration
Inspection And Packing
Flush, drain and individual packing
Checks Before It Ships
- Dimensional check of outer diameter, length, and inner diameter against the ordered code
- Pleat pack inspection for collapse, gaps, and end cap bond integrity
- Differential pressure check against the 4 bar at 21℃ rating
- O-ring compound and seating verification before packing
What We Can Change For You
- Length selected from 5 inch to 70 inch to match the installed housing
- Outer diameter chosen from 70 mm, 83 mm, or 130 mm to match the housing bore
- O-ring compound selected from Silicone, EPDM, Buna-N, or Viton based on fluid compatibility
- Adapter type confirmed based on the existing housing seat (round double O-ring or claw single O-ring)
- Private label printing and carton marking available for distributors
How It Compares With The Alternatives
| OEM branded depth pleated cartridges | Same dimensions and fit at a lower landed cost and shorter lead time, without the OEM warranty documentation |
|---|---|
| Melt blown or string wound cartridges | PP pleated offers higher dirt holding capacity and more consistent micron rating, but at a higher initial cost |
| Membrane pleated cartridges | PP pleated has lower absolute rating and higher flow capacity, but is not designed for sub-micron filtration |
| Metal cartridges | PP pleated is lower cost and lighter, but not suitable for high temperature or high pressure applications beyond 80℃ and 4 bar |
Installing And Running This Cartridge
- Confirm housing bore, seat type, and cartridge length before ordering; the adapter code must match
- Start clean differential pressure logging from day one so change-out is data driven
- Change out at 4 bar differential rather than waiting for the maximum rating
- Do not exceed 80℃; select Viton O-rings if the duty runs warm or carries aggressive chemicals
- Flush the housing before fitting a new element so settled solids do not load it immediately
- Lift the element vertically and keep it upright so captured solids stay on the pleat pack
