- Cure System: Anaerobic

- Ideal for machined metal components
- Perfect seal between components
- For gaps up to 0.25 mm
A 1-part instant adhesive ideal for tight fitting parts thanks to its very low-viscosity. Additionally delivers low-odor and low-bloom for aesthetic applications. LOCTITE® 408 is a low-odor, low-bloom instant adhesive. This very low-viscosity adhesive is ideal for tight fitting parts and applications where odor and/or blooming are a concern. LOCTITE 408 provides for rapid bonding of metals, elastomers and plastics, including difficult-to-bond plastics (PP, PE, PTFE) when used in conjunction with a primer such as LOCTITE® SF 770.
- Low-odor for applications where vapor control is vital
- Low-bloom for cosmetic applications
- Very low viscosity for close-fitting parts
- Bonds plastics, rubbers and metals

- Excellent motor oil resistance
- Forms tough, flexible, silicone rubber gasket
- Ideal for oil pans, transmission pans, valves and guides, differential covers
- Room Temperature Vulcanizing (RTV) curing

- Resistant to very high temperatures up to +980°C
- Protects from rust, corrosion, galling and seizing
- Unique brush top
- Used for screws, nuts, pipes, exhaust bolts and brake caliper bolts
- NLGI grade of 0

- For metals, most plastics and wood
- High service temperature
- Machinable and sandable
- Withstands extreme environments
- Low outgassing properties
- Room temperature cure
The Silver Anti-Seize Stick is a heavy-duty, temperature resistant, petroleum-based lubricant compound fortified with graphite and metallic flake. Will not evaporate or harden in extreme cold or heat. Use during assembly to prevent seizing, galling and corrosion. For use in assemblies up to 1600°F (871°C). Great for removal of spark plugs, cylinder head and exhaust head bolts.
