Loctite 518 is an anaerobic flange sealant that replaces cut gaskets on rigid metal flanges.
It cures between close-fitting metal faces. Therefore, it seals pump, gearbox and engine flanges. Follow the Henkel data sheet.
What is a Loctite 518?
Tapes and sealants protect, insulate and seal pipes, wires and joints. PVC tape wraps and insulates, while flange sealants such as Loctite 518 replace cut gaskets on rigid metal flanges.
Choosing the right product prevents leaks and corrosion. Therefore, check the surface, temperature and fluid before you buy.
