It is used in all drilling and anti-seize applications in the petroleum industry including refineries, petrochemical plants, and the water well industry. Liquid-O-Ring 221 Copper Seal II is recommended for use on all rotary shouldered connections and provides protection against galling and seizing or damage to threads on drill collars and tool joints, even under the most demanding conditions, including the deepest, hottest wells. It eliminates the need for wire brushing of threads to remove buildup often experienced with compounds that contain lead or zinc.<br \/>\nLiquid-O-Ring 221 Copper Seal II assures constant makeup torque, is effective when used on downhole production tools or pumping equipment, and is recommended for use in areas of high temperatures.<\/p>\n<p><strong><span style=\"color: #ff0000\">Applications<\/span><\/strong><\/p>\n<ul>\n<li>THREAD PREPARATION: MAKE SURE PIPE THREADS ARE CLEAN AND FREE OF ALL CONTAMINANTS. DO NOT apply 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<\/li>\n<li>APPLICATION INSTRUCTIONS: 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 4000 OCR Modified to thread protectors as well<\/li>\n<li>INSPECTION: One month after application of 4000 OCR Modified, thread protectors should be randomly removed and inspected for corrosion. Subsequent inspections are recommended every three months<\/li>\n<\/ul>\n<p><strong><span style=\"color: #ff0000\">Features, Advantages and Benefits<\/span><\/strong><br \/>\n1.Conforms to API RP 5A3\/ISO 13678<br \/>\n2.Lead-Free<br \/>\n3.Zinc-Free<br \/>\n4.Non-contaminating<br \/>\n5.Contains corrosion and H2S inhibitors<br \/>\n6.High temperature and high pressure rated<\/p>\n<p><strong><span style=\"color: #ff0000\">Typical Observations<\/span><\/strong><\/p>\n<p>Color: Copper<br \/>\nTexture: Smooth<br \/>\nDensity, lb\/gal@ 77\u00b0F (25\u00b0C): 10.25<br \/>\nSpeciffc Gravity @ 77\u00b0F (25\u00b0C): 1.23<br \/>\nDropping Point, ASTM D-2265: 500\u00b0F (260\u00b0C)<br \/>\nFlash Point, ASTM D-92: &gt;400\u00b0F (&gt;204\u00b0C)<br \/>\nPenetration, ASTM D-217 @ 77\u00b0F (25\u00b0C): 310\u2013330<br \/>\nBase Oil Viscosity<\/p>\n<p>cSt @ 40\u00b0C (104\u00b0C): 360<\/p>\n<p>cSt @ 100\u00b0C (212\u00b0F): 21<br \/>\nEvaporation Loss, ASTM D-972 @ 210\u00b0F (98\u00b0C): 0.2%<br \/>\nOil Separation, ASTM D-1742 @ 77\u00b0F (25\u00b0C): Nill<br \/>\n4-Ball, Weld Point, Kgf (ASTM D-2596): 620 Typical<br \/>\nSalt Spray Test, ASTM B-117: 500+ hours<br \/>\nTemperature Range: 0\u00b0F to 450\u00b0F (-18\u00b0C to 233\u00b0C)<br \/>\nFriction Factor, API RP 7A1: 1.15<br \/>\nBrushable To: 0\u00b0F (-18\u00b0C)<br \/>\nShelf Life (unopened container): Four years<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Liquid-O-Ring 221 Copper Seal II is a lead free, zinc free, quality lubricating compound that handles high temperatures and provides anti-seize performance required for breaking in new tool joints and lubricating drill collars.
