Nextflex tubular heaters are flexible heaters that are user formable, simple to install. These flexible heaters have an external sheath made of nickel braid and can be bent into virtually any shape. Nextflex tubular heaters are true to size heaters that do not expand when installed, eliminating risk of heated section outside of the manifold. Nexthermal can also assist you in selection, installation advice and improving application performance.

Nexthermal Tubular Heaters…
the next generation flexible tubular heater.
Heat Test: Previous generation flexible tubular heater (left) vs. the Nextflex (right). With Nextflex you are the clear winner.
Side by side test data demonstrates that Nextflex heaters transfer more heat to your tool. The chart shows that the Nextflex heater is very close to the tool temperature when our previous flexible heater shows a differential of more then 100Cº.

Efficient to Install
Nextflex tools reduce installation time and eliminate the need for additional retention methods.
Making sure heater is
directly above the groove,
strike with Teflon® side of
Nextflex forming tool.
One hard strike is better
than two soft ones.
Strike the Nextflex staking
tool hard every 20mm
(~.75"). This creates a
Firmly seated heater with
excellent heat transfer.
The first 10mm (~.40") after the connection area should always be straight.
For bending the Nextflex we recommend our Nextflex toolset. This will allow the Nextflex to be seated optimally into the groove, resulting in maximum heat transfer.
Form the first bend at
center location prior to
When bending, make sure the Nextflex tool handle is parallel with the uninstalled Nextflex. This puts the minimum bending radius protection in the correct position.
For optimal heat transfer, it is best to stake the Nextflex after assembly approximately every 20mm (~.75") into the groove.
