As a zinc-free, thread locking compound, Liquid-O-Ring 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.Liquid-O-Ring 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.
BENEFITS
🟢 Zinc-free
🟢 Environmentally friendly in cured form
🟢 Mixes easily
🟢 Workable consistency in excess of one hour
🟢 Water resistant
🟢 Oxidation resistant
🟢 Withstands high break-out torque
🟢 Provides a leakproof seal and strong permanent bond
🟢 Self lubricating
🟢 Unaffected by vibration, pounding or temperature
🟢 Excellent adhesion
APPLICATION
1. Thoroughly clean male and female threads to remove all thread dope, oil, and grease.
2. Dry threads completely prior to application of 252 Liqui-Lok Zinc-Free.
3. Thoroughly mix contents of can; add entire bottle of hardener and continue mixing until
completely uniform.
4. When used in conjunction with float equipment, apply 252 Liqui-Lok Zinc-Free to male threads
using a putty knife or spatula.
5. Make up joints final torque without delay.
NOTE
Setting action begins immediately after addition of the hardener. The mixture will remain in a workable consistency from 45 minutes to 2 hours under average conditions. Curing time may be reduced by elevating the temperature up to 250°F (121°C) or increased by lowering the temperature. The cure seal may be broken out by heating the joint to >550°F (287.8°C). Wet joints
or high moisture conditions may affect curing ability.
