Metric FIREROD Cartridge

Watlube Watlube is an electrically non-conductive lubricant that acts as a barrier against high temperature oxidation, thus making heater removal easier. In addition, it aids inthe transfer of heat from the metricFIREROD to the block. However, do not use it as a substitute for proper hole fit. Watlube is packaged in 118 ml (four ounce) bottles. To order, specify

6.4 mm (0.25 in.)No-Heat Individually Controlled Heat Zones Individually controlled heat zones give the flexibility of controlling temperature by zones, along the length of the metric FIREROD. This is an advantage for heating requirements of certain applications, like sealing bars. This internalconstruction can be ordered on 12.5,16 and 20 mm (0.5, 0.63 and 0.78 in.) diameter units.
