Termination Options:
1. Swaged-in Flexible Leads:
Swaged-in flexible leads with silicone-fiberglass insulation are ideal for applications requiring lead bending at the heater exit.
Unless specified otherwise, 250mm
(10 in.)
leads are standard issue.
Heaters 150mm
(6 in.)
or shorter typically feature a 6mm
(1/4 in.)
no-heat section. Heaters up to 250mm
(10 in.)
necessitate a 25mm

To order, specify flange, flange size, and desired location. .
Immersion Cartridge Heaters for Liquid Applications:
For optimal performance in liquid immersion heating applications, we recommend utilizing either brass or stainless steel threaded bushings.
The size of these threaded bushings is meticulously matched to the pipe diameter. Available specifications include
G thread, NPT thread, and BSPP thread , among others.
Step-by-Step Guide to Installing Cartridge Heaters:
1. Craft a precisely tailored hole within the section designated for heating.
2. Ream the hole to a smooth perfection for optimizing contact and maximizing heat transfer efficiency.
3. Extend the hole through the section to ensure hassle-free removal of the unit when needed.
4. If creating a through hole proves infeasible, adjust the hole size within allowable tolerances.
5. Minimize any vibration and flexing of lead wires to prolong the heater's service life.
6. Shield the heater's end to prevent liquid contamination and ensure durability.
Ensure a seamless order process for Cartridge Heaters by providing the following specifications: :
1. Specify the exact Type of Cartridge Heater (refer to Termination Options for guidance).
2. Accurately state the Diameter of the Cartridge Heater.
3. Indicate the Overall Length of the straight Cartridge Heaters.
4. Mention the required Wattage and Voltage specifications.
5. Detail the Type of Lead (glass fibre / PTFE) along with the desired Lead Length.
