1 in Threaded Rigid Conduit Union

The Appleton Century Crofts UNY100 is a galvanised steel expansion union for 1 in rigid conduit systems. It connects conduit to a box with female-to-male threaded ends in hazardous locations. The fitting carries Class I Division 1 and 2, Groups A through D, plus Class II and III ratings. Installers working in classified areas will find it suited to vertical or horizontal runs.

Thermals noise and power draw

As a passive steel fitting, the union generates no heat, emits no noise and draws no electrical power during operation. Its chromate, powder-coat and electroplated finishes resist corrosion without active cooling. The component simply maintains conduit continuity and grounding integrity in the installed raceway. No thermal management or power budget is required.

Hazardous-location rating and finish

The combined chromate, powder-coat and electroplated coating provides multi-layer corrosion protection for the iron body in harsh environments. The hazardous-location rating permits use in Class I, II and III divisions without additional sealing compounds. Threaded FNPT and MNPT ends allow direct assembly to conduit and boxes. No software or accessories are bundled with this fitting.

Questions about this item

How do I install the UNY100 rigid conduit union and what step is often missed?

Thread the 1 in FNPT end onto the box and the 1 in MNPT end onto the conduit, then tighten both joints to the torque value for 1 in rigid steel; the step often missed is applying thread compound rated for hazardous locations before assembly.

What maintenance or replacement will the UNY100 union need over time?

Inspect the chromate, powder and electroplated finish annually for corrosion; replace the union if the coating is breached or if threads show galling that prevents a tight hazardous-location seal.

What is the first limit that appears when the UNY100 union runs continuously in a Class I Division 1 area?

The 3 5/8 in overall length restricts thermal expansion travel, so the conduit system hits its movement limit before the union’s hazardous-location rating is exceeded.
