Standard Magnetic drain plugs trap worn gear material promoting fluid integrity. As the metallic components in transmissions and axles wear, they generate very fine particle debris that becomes suspended in the lubricating oil. A suspended magnet acts as a filter to contain these particles, keeping the fluid cleaner and extending component life. Periodic checking and cleaning of the magnet is recommended for maximum fluid service life. Depend on MAG-HYTEC when you’re pulling a heavy load!
