Liquid-O-Ring 4000 OCR Modified is a lead and zinc free superior alternative API Modified. Liquid-O-Ring 4000 OCR Modified is manufactured using components that meet or exceed the listed performance objectives in API RP 5A3/ISO 13678. These components are unaffected to chemical change and temperatures in excess of 500°F (260°C). Liquid-O-Ring 4000 OCR Modified is high pressure rated, provides excellent service characteristics in the areas of lubricity, sealing properties, make-up/breakout torque, and long term corrosion protection during periods of storage. Liquid-O-Ring 4000 OCR Modified contains corrosion and H2 S inhibitors for added protection to tubular threads.

Applications
1.THREAD PREPARATION: MAKE SURE PIPE THREADS ARE CLEAN AND FREE OF ALL CONTAMINANTS. DO NOT apply Liquid-O-Ring 4000 OCR Modified before proper conditioning has been done to pipe which has been exposed to H2S, CO2, or downhole chemicals. Carefully wash threads with Aqua Cure 690 to remove any salt deposits, residual chlorine from thread cutting operations, dirt, and grease. Use a stiff brush to remove all rust and corrosion. DRY THREADS COMPLETELY BEFORE APPLICATION. All residual water from cleaning procedure, re-threading operations, or hydrostatic testing should be completely dried and then treated using a moisture displacer such as 130 Moisture Displacer
2.APPLICATION INSTRUCTIONS: Liquid-O-Ring 4000 OCR Modified should be applied with a #2 Dope Brush or other equipment specifically designed for use with thread compounds (avoid using a paint brush). Use the dope brush bristles to force the compound into the roots of the threads. Take care to cover the entire threaded area. A VISUAL INSPECTION IS ADVISED. For optimum protection, apply Liquid-O-Ring 4000 OCR Modified to thread protectors as well
3.INSPECTION: One month after application of Liquid-O-Ring 4000 OCR Modified, thread protectors should be randomly removed and inspected for corrosion. Subsequent inspections are recommended every three months
