1/8th Inch Cartridge Heaters

durex 1/8th" cartridge heatersThe 1/8th Inch (3.175 mm) Magnum™ cartridge heater was developed for Original Equipment Manufacturers (OEMs) that required a small but high power thermal solution.

This miniature cartridge heater is designed with a thin 304 stainless steel wall for fast temperature response and is swaged for low internal temperatures and longer life. Additionally, Durex’ proprietary magnesium oxide (MgO) compaction process assures the highest possible dielectric strength. 1/8th Inch cartridge heaters can be used in applications up to 1000°F (538°C). Custom heaters can be designed in lengths up to 12 inches (305 mm), and 750 watts.
