Metal sheath elements are a versatile heating solution for solids, liquids, and gases. With a range of sizes, materials, and terminals in stock, Argus Heating can design an element to suit almost any application.

Features and benefits

  • Custom design and bend formations available to suit your application, to replicate an existing design, or repair a faulty element.
  • Heat wire spiral and cold length designed to match application.
  • Sheath can be protected from atmospheric corrosion and mechanical abuse.
  • Silicone resin or epoxy resin seal options available for moisture proofing the elements.
  • Various termination options available including stud, plain pin, quick connect, lead-wire, bulkhead fitting, locator washer etc.
  • Available with or without a custom mounting bracket.


  • Sheath can be manufactured in copper, stainless steel, Incoloy®, or titanium.
  • The sheath surrounds a helical coil of nickel- chrome resistance wire, centered and tightly compacted by an electrical insulator and heat transfer medium of magnesium oxide.
  • Argus Heating typically use Incoloy® for 6.7 mm diameter, titanium for 8 mm diameter, and Incoloy® 800 or Incoloy® 840 for 11 mm diameter.


Typically used for:

  • Heating platens for applications such as printing.
  • Constant heat for radiant and process heating.
  • High temperature heating for ovens and seal bars.
  • Immersion heating for liquids, gases, and chemicals.
  • Preventing ice formation in cooling and freezer units.
Also known as tubular heaters, metal sheath elements are available in a range of sizes, materials and terminals. We can design an element to suit any application.
