#POTW – Houghto-Safe 620E


Fire resistant hydraulic fluids, or FRHF’s for short, are widely manufactured using water glycol. This is a solution of a glycol (such as ethylene glycol) in water, with an additive package to help and improve viscosity, corrosion protection and anti-wear properties. Even though oil-based hydraulic fluids tend to have a high flash point, the risk of fire from ruptured lines is ever present. Using a FRHF, usually died red or pink to easily identify, is highly beneficial in applications such as; hot metal shears; electric welders; furnaces; diecasting machines and other applications where high temperatures  are present.
