Denso Void Filler is a petrolatum compound specially formulated for hot injection into voids. The compound is based entirely on petroleum hydrocarbons with additives to displace water, inhibit corrosion, enhance adhesion and control flow.


Denso Void Filler is pumped into the voids occurring between pipes, cables, ducts and protective sleeves to exclude air and water. It is generally pumped warm and sets to a semi-solid paste to provide corrosion protection of the steel.
