Modified-LZF™
Lead/Zinc-Free High-Pressure Thread Compound

MODIFIED-LZF is a patented, high-pressure sealant and anti-seize compound designed as a lead-free alternate for API-MODIFIED. MODIFIED-LZF, formerly known as ENVIRO-SAFE was first introduced into the market in 1989. The compound contains copper flake and graphite as well as other nonmetallic, inorganic, extreme pressure, and anti-wear additives. It has a balanced package of rust, corrosion, and oxidation inhibitors blended into a high-quality aluminum complex base grease. The aluminum complex grease provides a high melting point and excellent inherent water resistance; allowing it to stick to wet steel and ensuring that the compound will not wash off threads.

APPLICATIONS:
Recommended for use on premium and OCTG connections, flow lines, subsurface production tools, and tank battery installation. MODIFIED-LZF will lubricate, seal, and protect threaded connections of oilfield tubular goods on makeup, in service and in storage. The aluminum complex grease base is excellent for use on connections exposed to high concentrations of moisture.
- For a metal-free alternative and in applications using nickel or chrome alloy premium connections use SEAL-GUARD™.
