Reducing bushing for hazardous conduit

The Appleton Century Crofts aluminium bushing adapts a 4 inch male threaded conduit entry to a 2-1/2 inch female thread. It is rated for Class I Division 1 and 2 hazardous locations and suits IMC or threaded RMC installations.

Aluminium construction and plain finish

The lightweight aluminium body weighs 0.61 lb and resists corrosion in harsh industrial environments. The plain silver finish requires no extra coating and maintains conductivity for grounding continuity.

Threaded NPT connection limits

The 1 7/16 inch overall length fits tight enclosures but adds a fixed offset between conduit runs. The NPT taper seal demands proper thread engagement and cannot be combined with non-threaded or compression fittings.

Questions about this item

How often will the aluminum threads need re-taping or replacement?

The aluminum construction resists corrosion in hazardous locations, so threads typically do not require re-taping unless physically damaged during repeated conduit changes.

What is the first limit reached when conduit runs stay hot for hours?

The fitting is rated for Class I Division 1 and 2 environments; the limiting factor under sustained heat is the ambient temperature rating of the hazardous-location certification, not the bushing itself.

Does the bushing add noticeable heat or noise when the circuit runs continuously?

No — it is a passive aluminum fitting with no moving parts or electrical resistance, so it generates no noise and negligible heat during continuous operation.
