1. Condulet Conduit Outlet Boxes

GUA series conduit outlet boxes are installed within hazardous area conduit systems to:
  • protect conductors in threaded rigid conduit.
  • act as pull and splice boxes.
  • connect lengths of conduit.
  • change conduit direction.
  • provide access to conductors for maintenance and future system changes.
  • act as mounting outlets for fixtures (with appropriate covers).
  • act as sealing fittings (with appropriate covers).
Size Ranges:

  • Hub - 1/2" to 2".
  • Cover opening - 2" to 5" dia.

2. Terminator Cable Fittings

Terminator cable fittings are designed for use with Type MC cable – corrugated aluminum, interlocked aluminum and interlocked steel

Terminator cable fittings are installed:
  • to provide a means for terminating type MC and TC cable at junction boxes, control centers, panelboards and enclosures for motor control and electrical distribution equipment.
  • to form a mechanical watertight connection.
  • to provide ground continuity of cable armor.
  • indoors and outdoors in wet and dry locations.
  • in vertical and horizontal cable runs.
  • in non-hazardous and hazardous (classified) locations. Both TMC and TMCX series can be used in Class I and Class II, Division 2 locations. TMCX series may be used in Division 1 locations and when a seal is required.
TSC Epoxy Sealing Compound

A two part epoxy sealing compound is used to seal TMCX cable fittings. It is quick and easy to measure, mix and install. The compound is kneaded until a uniform color is obtained. It is then packed around the conductors and cable armor to effectively seal the cable.

3. GUB Junction Boxes

GUB series junction boxes are used in threaded rigid conduit systems in hazardous areas:
  • to function as a splice box, pull box or equipment and device enclosure.
  • indoors and outdoors.

4. EJB Junction Boxes & EJB Custom-Built Control Panels

EJB junction boxes are used in threaded rigid conduit systems in hazardous areas:
  • as a junction or pull box.
  • to provide enclosures for splices and branch circuit taps.
  • for housing terminal blocks, relays and other electrical devices.
  • indoors or outdoors in damp, wet, dusty, corrosive, hazardous locations.
  • where exposure to frequent or heavy rain, water, spray, moisture, and humidity is common; such as: offshore drilling facilities, cooling towers, coal preparation and handling facilities and sewage and waste water treatment plant.
  • in areas which are hazardous due to the presence of hydrogen or gases and vapors of equivalent hazard such as found in process industries, missile bases and gas manufacturing plants.

EJB custom-built control panels are used with EMP and EMPS barrel assemblies:
  • as a means of grouping control stations for centralized process control in hazardous areas in minimum space.
  • to provide the necessary pushbuttons, pilot lights, selector switches, tumbler switches and glass windows.

5. Unions and Elbows


UNY and UNF unions are installed in threaded thickwall conduit systems:
  • UNY – to connect conduit to a conduit fitting, junction box or device enclosure.
  • UNF – to connect conduit to conduit, or to provide a means for future modification of the conduit system.
UNA unions are used in conduit and fitting installations when entrance angle is between 90° and 180°.

EL elbows are installed in conduit run or in box or fitting hub:
  • to change direction in threaded rigid conduit run by 90°, or when terminating at a box or fitting.

6. Reducers and Plugs

RE and REC reducers are used in threaded heavy wall conduit systems.

RE reduces conduit hubs to a smaller size.

REA adapters enlarge drilled and tapped openings by 1 NPT size.

REC connects two different sizes of conduit together or is used to replace a coupling and reducer in an installation.

PLG plugs are used for closing threaded conduit hubs.

7. Couplings


EC couplings are used:
  • in hazardous areas where a flexible member is required in a conduit system to accomplish difficult bends, or to allow for movement or vibration of connected equipment or units.

8. Condulet Sealing Fittings, Chico Sealing Compound & Drains and Breathers

EYS and EZS sealing fittings:
  • restrict the passage of gases, vapors or flames from one portion of the electrical installation to another at atmospheric pressure and normal ambient temperatures.
  • limit explosions to the sealedoff enclosure.
  • limit precompression or ‘‘pressure piling’’ in conduit systems.
Size Ranges:

  • 1/2" - 6".

Chico X fiber:
  • forms a dam between the integral bushing of the sealing fitting and the end of the conduit and around the electrical conductors entering the hub
Chico A sealing compound:
  • forms a seal around each electrical conductor and between them and inside of the sealing fitting to restrict the passage of gases, vapors or flames through the sealing fitting at atmospheric pressure and at normal ambient temperatures
Chico® SpeedSealTM Compound:
  • designed to separate and form an explosionproof seal around each electrical conductor in Crouse-Hinds EYS and EYD sealing fittings.
  • restricts the passage of gasses, vapors or flames through the sealing fitting.
  • creates a seal for Class I, Division 1, Groups C & D and Class II, Division 1, Groups E, F & G hazardous areas.
Size Ranges:

  • Chico A compound – 1 lb. to 5 lbs. (provides 23-115 cubic inches of compound)
  • Chico X fiber – 2 oz. to 1 lb.
  • Chico A-P (5 pouches per carton) – provides 25 and 55 cubic inches of compound.
  • Chico SpeedSeal - 2 oz. or 6 oz. cartridge

Drains and Breathers:
  • ECD drains and breathers are installed in enclosures or conduit systems to: –provide ventilation to minimize condensation – drain accumulated condensate.
  • At least one breather should be used with each drain.
  • A breather is installed in top of enclosure or upper section of conduit system.
  • A ‘‘standard’’ drain is installed in bottom of enclosure or in lower section of conduit system.
  • ‘‘Universal’’ breather or drain functions as a breather when mounted at the top of an enclosure, or as a drain when mounted in the bottom of an enclosure.
  • ‘‘Combination’’ breather and drain is used in those applications where the use of a top mounted breather is not practical due to limited space; or in offshore and marine installations where moisture may enter the enclosure through the breather located on top of enclosure.
  • Drains and breathers are installed in hubs or drilled and tapped openings.
Size Ranges:

  • 1/4" - 1/2".
