About Adalet
Adalet Explosion-Proof EnclosuresMarmon/Berkshire Hathaway
Adalet was established in 1928 to manufacture conduit and cable fittings, and has spent nearly a century developing enclosure systems and cable accessories for hazardous and industrial environments. The company operates today as part of Marmon, a Berkshire Hathaway company, after previously being associated with the Scott Fetzer Company.
Adalet is a leading manufacturer of explosion-proof enclosure systems alongside industrial NEMA-rated non-metallic and sheet metal electrical enclosures. The engineered product range includes empty and populated explosion-proof and stainless steel junction boxes, motor control enclosures, meter and instrument housings, and increased-safety terminal and control enclosures, including the HazLo line for hazardous locations.
With more than 85 years of enclosure manufacturing experience and ISO-9001 certification, Adalet's catalog extends from basic junction boxes and meter housings up to panelboards and motor starters. The company serves oil and gas, chemical processing, water treatment, and power generation industries where NEMA 7 explosion-proof ratings and similar hazardous-location protections are required. ChatMRO helps electrical engineers and MRO teams match enclosure size, NEMA rating, and hazardous-location classification against the Adalet catalog, and our team supports RFQ submissions for plant maintenance or new installation orders.

Frequently asked questions
What does a NEMA 7 explosion-proof rating mean on an Adalet enclosure?
A NEMA 7 rating means the enclosure is designed to contain an internal explosion of flammable gases or vapors without igniting the surrounding atmosphere, making it suitable for Class I hazardous locations such as oil and gas or chemical processing facilities. Confirm your specific hazardous-location classification before selecting an enclosure.
What's the difference between Adalet's explosion-proof and general NEMA-rated enclosures?
Explosion-proof enclosures are engineered to contain internal ignition events in hazardous atmospheres, while general NEMA-rated enclosures (non-metallic or sheet metal) protect against environmental factors like dust, water, and corrosion without the same hazardous-location certification. Choose based on whether your installation site is classified as hazardous.
Does Adalet manufacture junction boxes in stainless steel?
Yes — the product line includes both empty and populated stainless steel junction boxes alongside explosion-proof variants, suitable for corrosive or washdown environments common in food processing and chemical plants. Specify your environment so the right material can be confirmed.
What industries typically specify Adalet enclosures?
Adalet enclosures are commonly specified in oil and gas, chemical processing, water treatment, and power generation industries, where hazardous locations and demanding environmental conditions require certified enclosure systems. If your facility falls into one of these sectors, our team can help confirm the right enclosure class.
How do I find the right Adalet enclosure without an exact model number?
Describe the required NEMA or hazardous-location rating, approximate enclosure dimensions, and intended use (junction box, motor control, or instrument housing), and ChatMRO's AI will match it against the indexed Adalet catalog. This is especially useful when replacing an enclosure in an older hazardous-location installation.
