N-7000 High Purity Anti-Seize
Metal-free formulation provides high levels of purity
and excellent lubricating properties. For Class 1, 2 and 3 power
plant hardware. Temperature resistant to 2400°F.
N-7000 is a specially formulated metal-free anti-seize lubricant
produced under 100% controlled conditions for highest purity.
N-7000 is formulated with high purity raw materials and
contains only trace levels of halogens, sulfur, copper,
aluminum and heavy metals. Developed to protect steel,
stainless steel and other proprietary alloys.
· Superior anti-seize: tests show stuck studs reduced by
· More uniform torque tension: smaller difference in torque
coefficients between bolting materials
· High purity: made from highest purity ingredients
· Free from copper: less than 50 ppm copper
· Typically used in applications with a dry surface
temperature of -29 to 1315ºC (-20 to 2400ºF)
· Bolts, studs, valves, pipe fittings, slip fits and press fits in
nuclear electric power generating plants, chemical plants,
pharmaceutical plants, paper mills and other locations
where stainless steel fasteners are used.
During assembly - prevents high friction, galling and seizing.
Promotes uniform and predictable clamping.
· During operation - high purity prevents stress corrosion
· Disassembly - prevents seizing, galling, destruction of
DIRECTIONS FOR USE
1. Before or during assembly, wipe brush onto threads and
other joint surfaces needing protection.
2. Use full strength. Do not thin.

An anti-seize lubricant used on a bolt helps to develop greater
clamp load for the same torque compared to an unlubricated
bolt. An additional benefit is greater uniformity in clamp load
among a series of bolts. The relationship between torque and
clamp load is expressed in the following equation:
T = K x F x D
· T = Torque (in-lb, ft-lb, N-m)
· K = Torque coefficient or nut factor, determine experimentally.
· F = Clamp Load (lb, N)
· D = Nominal diameter of bolt (in, ft, m)
K factors are obtained on Grade 8, 1/2 steel bolts and Grade 5
nuts by a test procedure which measures torque tension
properties. Lubricant was applied to the bolt threads and both
faces of the washer. See properties chart for the torque
coefficient or K value for the anti-seize compounds. We feel
that this data fairly represents performance to be expected.
However, the manufacturer makes no warranty of specific performance
on any individual fastener. In critical applications, it is
necessary to determine K values independently.
