A zinc-free, thread locking compound, 252 Liqui-Lok Zinc-Free is specially formulated to replace the welding of casing joints and threaded connections. This two-part epoxy compound is easily mixed under wide range of temperatures due to its workable consistency. 252 Liqui-Lok Zinc-Free is unaffected by vibration, pounding, or expansion due to temperature changes. It withstands high break-out torque and provides a leakproof seal.
