High-temperature anti-seize compound

COPASLIP™ is a high-performance compound specifically formulated to protect fasteners from seizure-induced by extremes of temperature, pressure, and corrosion. The semi-synthetic base fluid is reinforced with anti-oxidants, corrosion inhibitors, and ultra-pure copper particles to provide outstanding protection to threads and components.

COPASLIP™ minimises variations in frictional interference between threads, allowing accurate and consistent assembly. It also prevents galling and seizure during assembly and dismantling – even after long periods of exposure to high temperatures, corrosive environments or high pressure.

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
