Plastic Mesh Cores & Cages for Filter Elements


Dimensions of Rigid Mesh Cores & Cages from Industrial NettingExtruded plastic netting in rigid mesh tube form that provides structural support as a center core in filter cartridges. Rigid mesh cages are also used as outer containment sleeves to protect filter media from damage during handling and cleaning.

The ready availability of a wide range of configurations and the minimal tooling costs associated with custom designs make extruded mesh cores a favorite for filter design engineers.

Measurements & Tolerances

Plastic Rigid mesh tubes are extruded and stocked in common lengths with a "rough cut" length tolerance of +/-0.25".

To create more precise custom lengths extruded tubes can be "finished cut". The finished cut tolerance is +/-0.030" for lengths less than 46 inches or +/-0.060" for lengths from 46 to 94 inches.

Tube diameters can slightly differ from lot-to-lot due to shrinkage variability. Inside Diameter (ID) and Outside Diameter (OD) tolerances are typically +/-0.020" for most configurations.

Utilize our sonic welding service to bond fine, woven mesh or non-woven filter cloth to the surface of these Rigid Mesh Tubes to create an overwrapped tube.
