Series 3B fittings are compact pressure tight assemblies 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) or Series 3W/3Y (wire suspended electrode) to make a complete assembly.
Both 3B and 3H fittings are available with three different mounting threads, and are capable of withstanding up to 400 psig at 406°F.
Series 3H electrode fittings feature a one piece electrode core which can be trimmed to length in the field. One piece construction simplifies installation.
Both 3B and 3H fittings are available with three different mounting threads, and are capable of withstanding up to 400 psig at 406°F.
Series 3C side chamber fittings are cast iron or brass, pressure-tight
chambers containing up to 4 probes from 1-1/2" to 6" in length.
Pipe tappings provide connection to the side of boilers and pressure vessels to equalize the level in the chamber with the level in the vessel.
Series 3K fittings contain up to 4 probes and accommodate probes from 1-3/4" to 13" in length. Additional tappings are available for
tricocks and gauges.
Series 3E fittings are cast metal, pressure-tight assemblies 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 fl at surface atop open tanks
or closed vessels. 3N Fittings require the use of 3R rigid or 3W wire suspended electrodes.
Designed for general purpose service, Series 3F flanged, pressure-tight fittings can handle up to 7 probes. They mate with 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 to accommodate up to 7 probes and to mate with standard flanges on the tops of vessels.
The Series 3J Miniature Fitting has a 1" NPT body and housing. It is designed for applications where multiple probes are required in a small, non-pressured location. (For single probe applications, Gems recommends using a 3E1 fitting.)
Designed for use in food, beverage and pharmaceutical applications where cleanliness is vital. Two-piece Series 3M assemblies can handle
up to 4 probes. FDA-approved materials. Engineered for fast removal of fitting to facilitate cleaning and sterilization.
Series 3MT fittings are similar to 3M fittings, except they also feature Teflon®-covered probes with polished tips to meet the most demanding application requirements.
Available in Many Materials for Various Requirements
Adaptable for Various Fittings
For general purpose use, Series 3R probes are metallic rods with threaded ends that screw into a fitting that extends vertically down into
the liquid. Available in a variety of materials for different applications.
3T tapered rods are also available.
The 3S series electrode fitting is designed to provide isolation of electrodes from liquids containing solids, grease, soaps, sludge, rags,
paper and other debris commonly found in wastewater and sewage pumping applications.
Isolation is accomplished by enclosing wire suspended electrodes within a 1 1/2" galvanized pipe assembly with a neoprene flexible bulb installed on the lower end of the pipe. The bulb and pipe assemblies contain 3 1/2 quarts clean water with one ounce of sodium bicarbonate (baking soda).
When mounted in a sump, the pipe and bulb assembly is acted on by the hydrostatic pressure exerted by the liquid outside the bulb.

Series 3W probes, consisting of metallic bars within a protective plastic shield, are designed to be suspended above liquid with
PVC-insulated wires. They are ideal for applications where rigid electrode rods are impractical or cumbersome, such as:
Deep Wells
Pump Control
Waste Water
Deep Tanks
7/8" (2.22 cm) diameter x 3 3/4" (9.52 cm) length. 3Z1A wire and 3Z1B adaptor kit required for use with 3E, 3F and 3N fittings.

Series 3Y wire suspended probes consist of metallic bars within a protective plastic shield, designed to be suspended in liquid. Series
3Y suspension wires are PVC or Teflon® insulated for use in corrosive liquid applications. 7/8" (2.22 cm) diameter x 3 1/2" (8.90 cm) length.
