221AG Low Temperature Copper Seal
221AG Copper Seal II is a lead free, zinc free thread compound that is used in low temperature conditions. 221AG can be used on tool joints and drill collars, as well as for breaking in new tool joints. 221AG is recommended for use on all rotary shouldered connections, as well as on oilfield tubing and casing connections. There will be no metal buildup on the threads thereby eliminating wire brushing the connections after each run. The Friction Factor is 0.9 as determined by API -5A3/ ISO 13678, and conforms to API RP7G make-up charts. 221AG is not classified as a marine pollutant.
221AG assures consistent make-up torque, and is effective when used on downhole tools, or pumping equipment in low temperature application conditions.
