Magnetic Expansion Sealing Plugs

Product Description Our magnetic sealing plugs feature an integrated high-strength magnetic core designed to actively capture and retain metallic particles within the system fluid. This innovative component combines robust leak-proof seali...

Product Overview

The magnetic sealing plug integrates a magnet into its sealing structure: while plugging a process hole it also attracts metal debris in the flow passage, combining sealing with cleaning. Sealing reaches up to IP68, making it suitable for gearboxes and hydraulic systems where both plugging and control of ferromagnetic contaminants are required.

Technical Features

  • Integrated magnet captures metal debris at the same time
  • A dual sealing and cleaning function reduces wear in hydraulic components.
  • Sealing rating IP68 provides reliable water and dust protection.
  • Easy to install and removable for periodic inspection and swarf cleaning.
  • Carbon steel / stainless steel body to suit different corrosion-resistance needs.
