Anaerobic adhesives & threadlockers

Anaerobic adhesives. Threadlocker, flange gasket, shaft-hub

Anaerobic adhesives cure in the absence of air and in contact with metal. They are the industry standard for threadlockers, flange gaskets, shaft-hub connections , and pipe threads. We stock anaerobic adhesives from Permabond and Loctite.

Threadlockers according to strength class

Low-strength (removable by hand): for adjusting screws and frequent disassembly. Medium-strength (removable with tools): for standard connections, typically M6 to M20. High-strength (disassembly usually only possible with heat): for safety-critical connections in mechanical engineering and automotive technology.

Flange gaskets (FIPG)

Anaerobic flange sealants (formed-in-place gaskets) replace prefabricated gaskets. They fill irregularities up to 0.5 mm (product-specific) and, according to the manufacturer's documentation, are resistant to oils, coolants, and hydraulic fluids.

Shaft-hub connections

High-strength anaerobic adhesives secure bearings, bushings, and sleeves. Depending on the product, gap filling up to 0.25 mm and shear strengths up to 25 N/mm² are achieved according to the data sheet.

What matters when selecting

Strength class and disassembly, thread size and gap dimension, operating temperature and media contact as well as the substrate: passive surfaces such as stainless steel or coated parts may require an activator.
