Hazardous-Location Conduit Fitting

The Appleton Century Crofts stainless steel conduit fitting functions as both a drain and a breather for hazardous-location electrical systems. It carries a 1/2 inch male NPT thread on each end and suits 1/2 inch trade-size conduit. The plain silver finish resists corrosion in demanding industrial environments.

Drain and Breather Combination

A single body provides both drainage of condensation and pressure equalisation without additional components. The straight orientation simplifies routing in tight conduit runs. Class I Division 1 and 2 ratings cover Groups B, C and D, while Class II Division 1 and 2 ratings cover Groups E, F and G, plus Class III locations.

Threaded Connection Limits

The 1/2 inch MNPT threads restrict use to conduit systems with matching trade size and thread type. Overall length of 5.500 inches fixes the installed envelope and may not suit assemblies requiring a shorter or longer fitting. Buyers needing different thread sizes, alternative materials or non-hazardous ratings must select another product.

Questions about this item

Does the stainless steel body require any periodic replacement or maintenance in hazardous locations?

The stainless steel construction resists corrosion in Class I, Division 1 and 2 environments, so no scheduled replacement is needed under normal hazardous‑location service.

What limits continuous operation first — pressure buildup, condensation or thread seal integrity?

The fitting acts as both drain and breather, so condensation escape and pressure equalisation occur simultaneously; neither pressure nor moisture accumulates to a limiting level.

How much heat does the fitting add when it runs all day in a sealed conduit system?

The passive stainless steel body generates no heat of its own; it simply allows vapour to vent and remains at ambient temperature during continuous operation.
