COPPER SUPREME SPECIAL BLEND ®
Non-Lead/Non-Zinc Thread Compound
300 - 320 (ASTM D 217)
1.1 (per API RP 7A1)*
Copper flake, synthetic and
amorphous graphite, and other
Copper Supreme Special Blend has been developed as an answer to the environmental
restrictions and exposure concerns associated with the use of lead and zinc drill
collar/tool joint thread compounds. It contains copper flake combined with a proprietary
blend of amorphous and synthetic graphites, along with oxidation and H2S inhibitors, in
a high temperature base grease. In addition to the galling and seizing protection
provided by the solids, it also contains a soluble extreme pressure package that is
surface active (adheres to metal surfaces) and helps to provide the load carrying
capability required by the high bearing stresses present in rotary shouldered
connections. Copper Supreme Special Blend has a torque correction factor of 1.1 (10%
additional torque required) which will provide additional resistance to down-hole make-
up as compared to lead or zinc compounds. It applies easily in a wide range of
temperatures and conditions, is resistant to wash-out and will not harden or bleed
excessively in storage.
RECOMMENDED FOR all drilling applications (rotary-shouldered connections), including high
temperature environments. Also effective for use on open gear jackup legs.
*API RP 7A1: “Recommended Practice for Testing of Thread Compound for Rotary Shouldered Connections”
NOTE: Due to operation and equipment variables, this value may require adjustment based on field experience.
