1-1/2" Threaded Rigid Hub for RMC and IMC Conduit

This die-cast zinc hub connects threaded rigid metal conduit and intermediate metal conduit in electrical installations. The gray finish provides corrosion resistance for indoor and outdoor use. It is UL Listed and CSA certified for code-compliant work. The fitting includes an O-ring to maintain a rain-tight seal.

Replaces worn or missing hubs on junction boxes

The NPT female-to-male threads allow direct attachment to 1-1/2 inch trade-size conduit without adapters. Insulated throat protects conductors from abrasion during pulling. The jump is worth it when an existing fitting is damaged, corroded, or lacks the required rain-tight rating for the location.

Withstands sustained exposure to moisture

The zinc casting resists deformation under normal conduit torque and thermal cycling. The O-ring seal maintains integrity through temperature variation and vibration. Rain-tight construction prevents water ingress during prolonged outdoor exposure. The 0.73 lb weight reflects solid construction for long service life.

Questions about this item

What clearance does the 1-59/64" overall length need inside the enclosure?

The hub measures 1-59/64 inches long and requires a matching knockout plus space for the 2-23/32 inch square body to sit flush.

How do you seat the included O-ring when threading the 1-1/2" NPT female-to-male hub onto rigid conduit?

Start the hub by hand, compress the O-ring evenly, then tighten with a strap wrench until the rain-tight seal seats — do not use pipe wrench jaws on the die-cast zinc.

When should the gray die-cast zinc hub be inspected or replaced in an outdoor RMC/IMC run?

Check the O-ring and threads annually; replace the hub if the zinc shows white corrosion, the threads gall, or the rain-tight seal no longer holds.
