Overview
The Watlow G5A67 FIREROD cartridge heater is a precision heating element engineered for industrial, semiconductor, and process heating applications. With 240V supply and 750W power output, this 3/8″ diameter × 5″ length unit combines Watlow’s proven swaged cartridge design with premium materials to deliver consistent thermal performance. The FIREROD cartridge heater revolutionized the heating element industry in 1954 when it was patented as the first swaged cartridge heater, establishing the benchmark for reliability and durability in cartridge heating.
