Castrol Endurex® 4000 Plus is a NLGI 2 synthetic grease based upon advanced perfluoroether technology designed for critical "under-thehood" automotive applications which require "Sealed-for-Life" capabilities and a wide operating temperature range. The superior lowtemperature performance of Castrol Endurex® 4000 Plus provides improved response on winter days while maintaining high temperature performance.
Castrol Endurex® 4000 Plus can be used for hydraulic clutches, pistons, air pumps, fan clutches, anti-lock braking systems, and ball and roller bearing components, in static or dynamic conditions, which come in direct contact with fuel, brake fluid, and/or extreme temperatures. Additionally, this product may be used for reactive metal electrical contacts due to its low volatility and excellent oxidative stability.
