Nickel-free anti-seize compound


Molyslip FERROSLIP is an extreme high-temperature anti-seize compound formulated to protect fasteners from seizure induced by extremes of temperature, pressure and corrosion. The mineral-oil base fluid contains micronized particles of metallic and non-metal fillers to provide excellent lubrication and protection to threads and components.

Molyslip FERROSLIP is resistant to temperatures up to 1400°C and effectively protects against chemical corrosion and oxidation. Free of copper, lead, sulphides, fluorides, chlorides and nickel, FERROSLIP offers outstanding performance while minimising health, safety and environmental concerns. FERROSLIP is recommended for use on screws, flanges, nozzles, couplings and other metal fittings. FERROSLIP can be used on stainless steel and other hard metals such as titanium. The excellent lubricity of FERROSLIP minimises damage to the protective oxide layer to prevent pick-up during thread tightening.


• High temperature capability – up to 1400°C
• Ensures consistent friction between threads
• Protects against galling and seizure
• Protects against rust and corrosion
• Eases assembly of tight tolerance components
• Nickel free for improved health and safety


Molyslip FERROSLIP should be used as supplied. Ensure surfaces to be treated are clean and dry – free from oil, grease or dirt contamination. Apply a thin even coating by rubbing onto the surface with a lint free cloth.

When a compound is applied to a threaded fastener that will be tightened to a specific torque setting, the torque setting will require adjustment to allow for the lubricating effect of the compound. Failure to do so can result in incorrect tension in the fastener.

Correct torque settings can be calculated using the tables and charts below and the standard thread equation:


T = Torque (N.m), D = Diameter (m), P = Clamping force (N), K = Nut factor
