* Pull values are average on contact and Gauss values are peak on contact.
** Always consult a magnet professional before selecting thin wall tubes. Thin wall tubes are not recommended for products with abrasive characteristics or in manual clean designs such as grates.

Note: High-Temp magnets will have lower pull values versus standard temp design due to lower MGOe material

Magnetic Tubes

Tube Magnets

The product stream flows around one or more 1” diameter tube magnets located within the product streams that are attached to their housing via the tapped end holes. As tramp metal contaminants are captured, they move to the underside of the tubes, eliminating tramp metal “wash-off”. Magnetic Tubes are easy to install and clean. They offer an efficient and economical ferrous metal filtration protection of your processing equipment. The tubes may be used as individual units or part of multiple row arrangements.

Magnetic Tube Bar Magnet
  1. All tube ends are fully welded for the highest durability and sanitary design, no crimped or mechanically sealed end plugs
  • Heavy wall thickness tube for high durability, higher performance thin tubes available and summarized in the table below
  • Multiple designs to fit every budget and performance requirement
  • Exclusive coatings available for nonstick and abrasive applications
  • Made in the USA

MPI can manufacture your tube with any end plug required for easy installation into your application.

  • Tube end design (end 1):
    • ¼-20 tapped (standard)
    • 3/8-20 tapped
    • Plain end
    • Bullet nose end
    • Bullet nose end ¼-20 tapped
    • Customer specified

    • 3/8-20 tapped
    • Plain end
    • Bullet nose end
    • Bullet nose end ¼-20 tapped
    • Customer specified

MPI can manufacture your tubes with dead space on one or both ends to make metal removal easier. Note that there will be no magnetic protection in the dead space area and therefore should be located outside of the product flow area.

  • Dead space length:
    • No dead space, full magnetic tube (standard)
    • 2” dead space (slightly magnetic at end of the tube)
    • 4” dead space (no residual magnetism at end of the tube)
  • Dead space location:
    • Not applicable
    • End 1
    • End 2
    • Both ends
