Fyrquel® 220 MLT is a pure synthetic phosphate ester fluid manufactured to conform with military specification MIL-H-19457D (SH). Like all phosphate ester fire resistant fluids, Fyrquel® 220 MLT offers users superior fire protection due to its unique self extinguishing fire properties. Other non aqueous synthetic fluids, such as polyol esters and polyalkylene glycols/polyol ethers continue to burn after ignition and are not self extinguishing. Fyrquel® 220 MLT phosphate ester self extinguishes as soon as the source of ignition is removed. SOLD IN 5-GAL PAILS. SHIPPING WILL BE CHARGED SEPARATELY. EXCISE TAXES ARE NOT INCLUDED.
