Loctite 243 blue adhesive - threadlocker for securing metal screw threads, medium strength, universal, protects against vibration loosening of components, for metals, stainless steel, aluminum, P1 NSF approval
Description
Properties
Loctite 243 is a medium removable adhesive to protect threaded connections against unscrewing and loosening due to vibrations. Traditional safety methods such as: spring washers, nuts with nylon insert, etc. over time, they loosen. Loctite 243 is resistant to vibrations and temperature changes - it does not lose stress as a result of them, which perfectly prevents loosening of joints.
Benefits of using
- excellent joints protection against unscrewing and loosening under the influence of vibrations
- food contact approval - NSF P1
- greater reliability
- lower costs
- possible disassembly
- prevents baking and corrosion
- reduces storage costs
- very good resistance to chemicals and high temperatures
Loctite 243 fills all free spaces in the thread

Use
Protection of threaded connections against unscrewing, wherever the possibility of subsequent disassembly is necessary.
