Termination Options:
1. Swaged-in Flexible Leads:
Swaged-in flexible leads with silicone-fiberglass insulation are recommended for applications where the leads must be bent at the exit point from the heater.
Unless a longer length is specified, 250mm
(10 in.)
leads are supplied.
Heaters 150mm
(6 in.)
or shorter generally have a 6mm
(1/4 in.)
no-heat section. Heaters up to 250mm
(10 in.)
require a 25mm
(1 in.)
no-heat section. Heaters greater than 250mm may require more than a 25mm no-heat section. To order, please specifyswaged-in flexible leads.
2. Right Angle Leads:
Right angle leads are used in applications with a high degree of flexing and when space limitations are critical. Lead wires exit at a 90° angle through the side of the heater sheath.
A right-angle tube may be necessary for certain constructions. To order, specifyright angle leads and lead length.

Unless otherwise specified, our standard leads measure 250 mm
(10 in.)
in length. The stainless steel braid is 200 mm
(8 in.)
long. To customize your order, please specify your preference for straight or right-angle stainless steel braid, lead length, and no-heat section requirements.

Our ceramic bead insulation offers exceptional lead protection in high-temperature environments exceeding 450°C(840°F).The ceramic beads fit over solid conductors and extend to cooler areas where flexible wires can be securely attached. To order, specify ceramic beads and length, and additional lead length requirements.
7. Versatile Stainless Steel Flanges
Our stainless steel flanges provide a convenient mounting method and an effective way to position heaters within applications. Flange style and specifications are tailored to customer requirements. These flanges can be placed in any no-heat section of the heater sheath. To order, specify flange, flange size, and location. .
Immersion Cartridge Heaters for Liquid Applications:
For liquid immersion heating applications, we recommend using brass or stainless steel threaded bushings.
The size of the threaded bushing is matched according to the pipe diameter. Available specifications include
G thread, NPT thread, and BSPP thread , among others.
Step-by-Step Guide for Seamless Installation of Cartridge Heaters:
1. Begin by creating a precise hole in the desired section to ensure optimal heating.
2. Ream the hole to achieve smoothness, enhancing contact and heat transfer efficiency.
3. Extend the hole through the section to facilitate easy removal of the unit when necessary.
4. If a through hole is impractical, adjust the hole size within acceptable tolerances.
5. Minimize vibration and flexing of lead wires to prolong the heater's service life.
6. Protect the heater's end to prevent liquid contamination and ensure longevity.
