Heating element won't let go

Durex Industries has developed a mini coil heater with a novel clamping band which allows the heating element to maintain full clamping force at elevated temperatures.
Durex Industries has a mini coil heater with a novel clamping band which allows the heating element to maintain full clamping force at elevated temperatures.
Unlike conventional cam-locking designs, this wedge-locking mechanism compensates for thermal expansion.
The tubular heating element is constructed in a rectangular profile to significantly increase surface contact of the heater and injection nozzle, resulting in a more efficient heat transfer.
A standard Allen wrench tightens the wedge lock clamping mechanism to user requirements, another advantage over the cam-locking designs.
Flexible element extensions terminate to Teflon leadwires with moisture-resistant seals.
Each coil heater is manufactured by Durex with a resistance tolerance of +/-2%.
Standard sizes in 0.75in diameter and 1.2in length are in stock in various wattages and can be supplied with a Type J or K thermocouple.
