250 Rigid Union for Conduit Systems
The Appleton Century Crofts UNF250R is a straight union designed to join two sections of rigid conduit. It features female-to-female threaded ends sized for 2-1/2 inch trade size conduit in vertical or horizontal runs. The malleable iron body provides mechanical strength for industrial and commercial electrical installations. This new fitting is chromate coated, powder coated and electroplated for corrosion resistance.
Thermals Noise and Power Draw in Normal Use
As a passive conduit fitting the union generates no heat, produces no audible noise and draws no electrical power. Its function is solely to maintain a continuous raceway between conduit sections. The coated iron construction withstands ambient temperature extremes typical of industrial environments without degradation. No active cooling or power budget is required for this component.
Replaces Worn or Damaged Conduit Unions
This union replaces a damaged or corroded straight coupling in an existing 2-1/2 inch rigid conduit system. The upgrade is worth it when the original fitting shows thread wear, coating failure or physical deformation that compromises the raceway integrity. It is not for buyers who need a different trade size, a reducing union or a fitting compatible with flexible conduit types.

Questions about this item
How do I install the UNF250R rigid union between two conduit runs?
Thread each 2-1/2 in FNPT end onto the matching rigid conduit until hand-tight, then tighten with a strap wrench until the faces meet squarely; the step often missed is confirming both conduit ends are cut square and reamed so threads engage fully.
What maintenance or replacement will the UNF250R need over time?
Inspect the chromate, powder and electroplated finish annually for coating damage; if white or red corrosion appears on the malleable iron body, replace the union to maintain grounding continuity.
What limit appears first when the UNF250R sees continuous vibration?
The rigid malleable iron body transmits vibration directly to the threaded joints, so fastener loosening at the FNPT connections is the first failure mode under sustained mechanical shock.
