Plastic Mesh Cores & Containment for Filtration

Use extruded mesh plastic tubes as center core supports and outer cages to build your cartridge filters.  Nearly 100 configurations of diameter, wall thickness and open area are available from stock.  Unlike molded tubes, minimal tooling costs are required for custom designs.  Get the right combination of flow characteristics and structural support.

Rigid Mesh Tube measurements by Industrial Netting

Rigid plastic tubes are extruded to produce fixed apertures with maximum dimensional stability.  Most cores are made from polypropylene resin that complies with FDA regulations for food contact.  Industrial Netting plastic cores are used in cartridges and as components for air, liquid and gas separation and filtration.

Common lengths are in stock for immediate shipment - or have us precision cut to your required sizes.  Contact us for more information or to request a quote.

Tolerance capabilities are impacted by tube diameter, wall thickness, strand configuration and cut length. Please consult your Industrial Netting representative for specific tolerances achievable on your plastic rigid mesh tube.
