High Density Foam Sponge Cubes for Concrete Pump Clean-Out

These clean-out foam sponge cubes are made from open-cell polyurethane foam and are used to clear concrete lines after pumping. When inserted with a washout cap, air or water pressure drives the sponge through the hose or pipe, sweeping out leftover material and helping keep lines clear. For custom-size foam cubes please send us email Contact Us. We ship Australia wide.
