Specifically formulated to meet performance requirements of proprietary, metal-to-metal seal, and high interference connection designs utilizing high performance materials including super chrome and high-alloys steels. HPHT THREAD COMPOUND's formulation contains a small percentage of PTFE to aid high temperature sealing properties. The particle size of the PTFE is controlled to allow it to seal 8-round and buttress thread forms. Its advanced base grease is a carefully selected balance of synthetic oils with an advanced biodegradable grease thickener technology. The base grease provides excellent adhesion and stability yet biodegrades and is environmentally safe based upon the Harmonised Offshore Chemical Notification Format (HOCNF) guidelines. Tubing connections ideal for 8-round and premium mechanical.
