BESTOLIFE® ZN-50, available from Scarlet International, is a high-performance zinc-based thread compound formulated for rotary-shouldered connections in oil and gas drilling. Designed for use on tool joints, drill collars, and coring bits, it offers excellent protection against galling and seizing under high-pressure conditions. With a gray color, consistent brushability down to 10°F (-12°C), and a high flash point of ≥485°F (≥252°C), ZN-50 performs reliably in extreme environments. Containing zinc and non-metallic additives, it ensures long-lasting lubrication and thread protection, making it a trusted solution for demanding drilling operations.
