ExxonMobil Exterex™ A51 Synthetic Fluid
Categories:	Fluid; Lubricant
Material Notes:	Product Description: Esterex™ Adipate Esters are API category Group V fluids. These esters have excellent low-temperature properties, high viscosity indices, good lubricating properties and low volatilities. Esterex™ Adipate Esters can be used as sole basestocks or blendstocks with other synthetic fluids in many automotive and industrial lubricant applications. These esters are ideal in high-temperature conditions, such as reciprocating air compressors, where discharge valve cleanliness is required. Appearance: Bright & Clear Availability: Africa & Middle East, Asia Pacific, Central America, Europe, North America and South America Information provided by ExxonMobil
