Our Thread Lockers, Pipe Sealants and Liquid Gasket Adhesives are all Anaerobic Adhesives; special types of adhesive that cure only when deprived of air. This makes them perfect for sealing and sealing and locking threaded connections, close fitting pipes, bearing housings and other precision metal parts. They can even be used to create liquid gaskets on things like compressors. Our range of Weiconlock Anaerobic Adhesives include grades suitable for all kinds of applications and are all German engineered and made.
