339 Seal Supreme is a premium thread compound manufactured for application to self-sealing connections. This nonmetallic thread compound is manufactured using a proprietary blend of non-metallic additives with a high temperature lithium complex grease and TeflonŽ** to provide a product that protects against galling and seizing and is inert to chemical attack. 339 Seal Supreme is an environmental alternative to API compounds, or other commonly used compounds that contain metals such as zinc or copper. A state of the art corrosion inhibitor package allows 339 Seal Supreme to provide protection against many downhole chemicals or harsh contaminants. 339 Seal Supreme protects against thread damage while effectively sealing at temperatures of 400°F (>204°C).
