Metal Free is an economical, nonmetallic thread compound developed to meet or
exceed the performance objectives of API RP 5A3 when used on API OCTG and
Buttress connections and conforms to ISO 13678. It contains a proprietary blend of
synthetic and amorphous graphites and fine Teflon® powder that is inert to chemical
attack. Metal Free will protect against galling and thread damage and seal effectively to
pressures as high as 10,000 psi and temperatures in excess of 300°F. It contains no
toxic materials that exceed the regulatory limits established by the EPA or by the
California hazardous waste regulations.
Recommended for all API casing, tubing, line pipe, and Buttress connections
*The proper field torque for all API casing and tubing connections should be determined by
following the procedures outlined in API RP 5C1: “Recommended Practice for Care and Use of
Casing and Tubing”.
DO NOT USE ON OXYGEN LINES OR IN OXYGEN ENRICHED ATMOSPHERES.
