Quaker Houghton Houghto-Safe 620 E

HOUGHTO-SAFE 620 E is a premium performance, water containing, synthetic hydraulic fluid.
It greatly reduces risks where hydraulic equipment operates near flames, hot surfaces or molten metals.

HOUGHTO-SAFE 620 E is particularly suited to oil hydraulic systems that require a balanced combination of fire resistance and good lubrication.
It has for over 50 years set a global benchmark in steel and aluminium production, pressure die-casting, glassmaking, polymer forming and many other high-fire-risk industries.

o High security against fire
o Increased operator safety
o Lower insurance premiums
o Increased plant security and availability
o Increased productivity
