Weiconlock AN 302-43 Thread Locking Adhesive is a blue anaerobic threadlocker designed to permanently lock and seal threaded connections and prevent against unwanted loosening. This thread locking compound has a medium strength rating which means its bond will be able to be broken with normal tools when it is required for disassembly. It also has a high viscosity which allows it to be accurately applied to small diameter threads and reduces the risk of mess and spillage.

AN 302-43 is a high quality threadlocking compound that does not permanently mark threads it is applied to and is made in Germany. It has been approved by DVGW for use in gas line applications and systems and is NSF/ANSI 61 certified for use with drinking water.

This quality anaerobic adhesive is very easy to use thanks to the unique pen system used for all our Weiconlock thread lockers, pipe sealants and liquid gaskets. It allows you to grip the bottle like you would a pen and makes accurate application very simple. To see it in action, check out the media tab on this page which features a demonstration video for our Weiconlock AN 302-43.

What do I have to do to prepare the surfaces?

Clean and dry as much as possible. Weiconlock grades will work on slightly oily surfaces but adhesion will be improved on parts that have been cleaned and degreased.

How long does it take to dry?

About 1-3 hours at room temperature for complete curing. Handling strength (usually around 35% of the final strength) will be achieved much faster; about 10-20 minutes at room temperature.

The large range quoted here is a reflection of two things; the difference in what room temperature can mean and the fact that Weiconlock AN 302-43 will take slightly longer to cure on some surfaces than others.
