Description

Designed for general purpose service, Series 3F flanged,
pressure-tight fittings can handle up to 7 probes. They matewith standard pipe flanges coupled to the top of the vessel.
Available in a variety of materials.

Series 3G fittings are designed for general purpose
use, and are made of PVC to withstand corrosive
conditions. The flanged assemblies are sized toaccommodate up to 7 probes and to mate withstandard flanges on the tops of vessels.

Series 3E fittings are cast metal, pressure-tightassemblies capable of handling 1-7 probes.
Attachment to vessels is accomplished with external
pipe threading. 3E Fittings require the use of 3R
rigid or 3W wire suspended electrodes.

Series 3N fittings accommodate 1-3 probes
operating at atmospheric pressure. The assembly
mounts on a flat surface atop open tanks or closed
vessels. 3N Fittings require the use of 3R rigid or
3W wire suspended electrodes.

Series 3B fittings are compact pressure tightassemblies that hold a single electrode probe
for use in water and chemicals. These fittings
incorporate a 1/4-20 female thread that must be
combined with a Series 3R (rigid rod electrode) orSeries 3W/3Y (wire suspended electrode) to make acomplete assembly.
