60% Lead Drill Collar Compound

Chemola™ ThredOn™ 306 Heavy DC is a heavy duty drill collar compound containing a minimum of 60% atomized lead powder. Heavy DC is resistant to vibration, contraction or expansion of tool joints and can be used as a lubricant and sealant for all threaded connections. Heavy DC prevents metal to metal contact, eliminates galling and seizure of threads. It provides a tight, leak-proof seal under high temperature and pressures and protects threads against corrosion. Heavy DC conforms to the requirements and standards of API Spec. 7, Appendix F, May, 1979.

Recommended Uses

Heavy DC is specifically formulated for use on drill collar rotary shoulder connections and is also great for drill pipe.
