Square Cartridge Heaters

• Available in .375", .500" and .625" diameters

• Right angle leads are ideal for applications where space is limited.
• Leads are covered with silicone impregnated fiberglass sleeve where they exit the heater.
• When ordering, please specify the overall length.

• Swaged in stainless steel braid provides excellent abrasion protection while allowing the leads to be bent in a tight radius.
• Because the braid is swaged in, it is extremely resistant to pulling out of the heater.

• Right angle stainless steel braid offers the same advantages as swaged in stainless steel braid, but allows use in tight spaces. 
• When ordering, please specify the overall length.

• Flexible conduit (also known as armor or hose) provides maximum lead protection from abrasion but cannot be bent quite as sharply as stainless steel braid.
• Flexible conduit is swaged into the heater for maximum protection.

• Right angle stainless steel conduit offers the advantages as swaged in stainless steel conduit but allows use in tight spaces.
• When ordering, please specify the overall length.

Tab Stops are ideal for preventing heaters from sliding too far into the hole.

• RTV Potting, when used in combination with silicone rubber insulated lead wire, provides the best seal of all options.
• The down side to silicone is that it is limited to 500ºF and while extremely flexible, it is not as strong mechanically as other options.
• Although the RTV is rated for 500ºF, silicone rubber leads are only rated to 392ºF. An option is to use Duraflex lead wire instead. Duraflex is rated to 1000ºF and has a heavy silicone coating.
• While Duraflex is not sold as a waterproof wire, it performs very well in wet environments.
• Another option is to use crimped on leads, then the power pins are sealed where they enter the heater and the type of lead wire does not matter.
