Key parameters
Product Family
FIREROD swaged cartridge heaters for insertion heating
Diameters
Standard imperial diameters from 1/8 in through 1 in and metric equivalents (per diameter-specific sheets)
Sheath Temperature
Up to approximately 1400 °F (760 °C) depending on sheath material and watt density
Sheath Materials
Incoloy / stainless steel options typical for FIREROD
Watt Density
High watt density swaged construction for compact high-power heating
Voltage
Common ratings 120/240/480 VAC; other voltages configurable
Fits high-watt-density insertion heating where you need a Watlow FIREROD swaged cartridge with precision OD, sheath options to about 1400 °F (760 °C), and configurable leads.
Key advantages
- Family — FIREROD swaged cartridge heaters for insertion heating
- Diameters — Standard imperial 1/8 in through 1 in and metric equivalents
- Temperature — Sheath up to ~1400 °F (760 °C) depending on material/watt density
- Construction — Swaged MgO; Incoloy/SS sheath options
- Options — Distributed wattage, dual voltage, thermocouple-in-heater, special seals
Typical applications
- Plastics, packaging, and food equipment.
- Dies, platens, and medical devices.
- Tight-bore insertion with SELECT Visual Designer configs.
Selection guide
- OD / length — Bore diameter and heated length
- V / W — Match watt density to material
- Leads / seals — Crimped, swaged, moisture-resistant
- TC — Thermocouple-in-heater yes/no
Common mistakes
- Loose bore fit causing hot spots.
- Oversizing watt density for low-conductivity materials.
- Ignoring lead temperature rating.
When to RFQ / what to tell us
- OD, length, V/W, lead style.
- Sheath; TC; quantity; ship-to.
