Loctite 51007 C5-A Copper Anti-Seize 454g

Loctite LB 8008 C5-A (part 51007) is a non-curing, copper-coloured anti-seize paste. It shields mated parts from high-temperature seizing and galling, so studs, bolts, flanges and gaskets come apart more easily and in cleaner, better condition.

It suits maintenance work in petroleum and chemical plants, steel mills, power plants, marine and foundries. It suits copper, brass, cast iron, steel and all alloys including stainless steel.

Where this product is used

• Studs, bolts, nuts and flanges exposed to high temperature
• Exhaust manifold and brake calliper bolts
• Flanges and gaskets in petroleum and chemical plants
• Fixings in steel mills, power plants and foundries
• Marine fittings

Features

• Shields against high-temperature seizing and galling
• Smooth copper-coloured paste, non-curing
• Typical operating range -29 °C to +982 °C
• Torque coefficient K of 0.16 on 1/2" grade 8 steel bolts with grade 5 nuts, against 0.27 solvent cleaned and not lubricated
• Helps develop greater clamp load for the same torque, with more uniform clamp load across a series of bolts
• Suits copper, brass, cast iron, steel and alloys including stainless steel

Using it

Make sure the mating surfaces are clean and free of grease.

Apply a thin coating to the threads and flats of the nuts and bolts, then assemble.

Torque follows T = K x F x D, where K is the torque coefficient, F the clamp force and D the bolt diameter. Wear a dust mask when grinding or wire brushing.

Copper, brass, cast iron, steel and all alloys including stainless steel, plus plastics and non-metallic gasketing materials.

It is not recommended for pure oxygen or oxygen-rich systems.

Storage and handling

Store the unopened container in a dry location, optimally between 8 °C and 21 °C. Storage below 8 °C or above 28 °C can adversely affect the properties of the product.

Limits and safety

Not recommended for pure oxygen or oxygen-rich systems, or as a sealant for chlorine or other strong oxidisers. Read the safety data sheet before use.
