Longlife SRL-50 – Sucker Rod Lubricant
Longlife SRL-50 – Sucker Rod Lubricant
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 oxidation at elevated temperatures with exceptional performance under extreme low temperature conditions. SRL-50 contains EP/anti-wear additives and rust and oxidation inhibitors that provide superior protection from thread galling in sucker rod connections.
Application
Clean the connection prior to make up. Apply a thin coat of SRL-50 to the thread.
CAUTION: Do not lubricate the pin shoulder face or the coupling shoulder face or a loss of tightness can occur resulting in a connection failure.
