BESTOLIFE® Copper Supreme Special Blend® Plus (CSSB Plus), offered by Scarlet International, is a high-performance copper-based thread compound engineered for extreme drilling conditions. Enhanced with a proprietary corrosion inhibitor, it provides superior protection during both operation and storage. Ideal for high-temperature applications on drill collars, drill pipe, and rotary-shouldered connections, CSSB Plus resists washout, prevents hardening, and remains brushable in cold conditions. With proven performance in salt spray resistance and a shelf life of up to 4 years, it’s also effective for rig components like jacking systems and slides.
