Longlife SRL-50 is engineered to protect the threads of sucker rod connections under severe operating conditions of high cyclic loading. SRL-50 is a high temperature, lithium complex EP grease with excellent low temperature properties. SRL-50 is a unique blend of petroleum base oils and synthetic fluids providing excellent resistance to oxida-tion at elevated temperatures with exceptional performance under extreme low temperature conditions. SRL-50 contains EP/antiwear additives, rust and oxidation inhibitors that provide superior protection form thread galling in sucker rod connections
