IMMERSION WELLS AND PACKING NUT
½
”
and ¾
”
NPT Sizes for Hydronic Element Insertion
FEATURES
• Wells are used where it is desired that the control operates from the temperature
of a liquid in a closed system.
• The bulb of the control can be removed from an immersion well in the tank wall
without draining the boiler tank.
• The packing nut can be used with any of the remote bulb types listed.
• Packing nuts permit closer control than wells because the bulb is directly immersed
in the liquid.
SPECIFICATIONS
Compatibility . . . . . . . . . . . For use in liquids that are not corrosive to
brass and copper. Not recommended
for use above 100 psi, 250°F (120°C)
