Filter Cores & Tubes by Industrial Netting

Sonically Welded
Tube Overwraps

Custom Fabricated
Tubes

Rigid Polypropylene Tubes
Rigid mesh tubes provide structural support for filter cartridges One of the main applications for plastic netting (in rigid tube form) is for center core support in filter cartridges. Extruded cores are common in all types of cartridge filtration, whether pleated, wound or depth filter elements. The ready availability of a wide range of product designs, and the minimal tooling costs associated with custom designs, make extruded cores a favorite for filter design engineers.

Rigid tubes can be used as an outer containment sleeve for cartridge filters as well. The tubes protect filter media from damage during handling and cleaning.

Below is a list of current extruded rigid tubes made from polypropylene or polyethylene. If you do not see what you need, please contact us to further explore our capability.

We can also custom fabricate tubes to larger diameters from a variety of flat mesh or nonwoven products or bond nonwovens to the outer surface of rigid tubes using our sonic welding capabilities.
