Esterex™ A51

Esterex™ A51 is a API category Group V fluids. Esterex™ A51 has excellent low temperature properties, high viscosity indices, good lubricating properties, and low volatilities. Esterex™ A51 can be used as sole basestocks or blendstocks with other synthetic fluids in many automotive and industrial lubricant applications. Esterex™ A51 is ideal in high temperature conditions, such as reciprocating air compressors, where discharge valve cleanliness is required.
