Cooling neck and connection head

If the process already has a welded thermowell, a suitable cooling neck and connection head can be purchased as a separate component. Cooling necks have outer threads which can be applied to D-wells:

• M14×1,5 for D1S and D4S
• M18×1,5 for D1, D4 and D5.

Cooling necks and connection heads, as components (without wells, without sensing elements):
