"Metal to Metal Liquid Tight Seal"
Features and Benefits
• Increased heater life
• Less down time
• No need for a soft start due to
moisture penetration
• Ability to use a cartridge heater where not possible before
• Abrasion and vibration resistant
• Able to be formed or bent to fit
the contours of wiring raceways
• No additional insulation of lead wires is needed to protect against high temperatures
• Lead cables and seal will not out-gas in vacuum environments
The Watlow FIREROD with the patented MI lead and seal option is
MI leads handle both high temperatures and contamination, and resist other problems like abrasion and excessive vibration. The metal seal and swaged-in, formable MI cable leads are capable of handling temperatures up to 815°C (1500°F). In addition, the lead end seal resists moisture and other forms of contamination, including plastic drool/flash, gases, oils, solvents and water.
covered by a two-year limited warranty. This extended warranty for this product only applies to manufacturing defects or failures due to over-temperature or product failure due to contamination.
This LA option is also available as a manufactured item. Specify MI leads and seal, as well as volts, watts, cable length, lead length and type. 152 mm (6 in.) of MI cable and 305 mm (l2 in.) of Teflon® leads will be supplied unless otherwise specified. To order, specify option code J.
Applications
• Injection molding
• Vacuum forming
