Eaton PLG85 SA Conduit Plug - Hazardous Locations
Part Number: PLG85 SA
Quick Summary
PLG85 SA conduit plug from Eaton Crouse-Hinds seals rigid/IMC conduits in hazardous locations for reliable, code-compliant terminations. Many teams struggle with protecting electrical terminations from dust, moisture, and arc hazards in exposed environments. This solution supports NEC/CEC compliance and UL-certified explosion-proof performance, with an area classification of Hazardous/Classified Locations. The copper-free aluminum construction reduces weight and corrosion risk, while the 3" trade size and square-head design speed installation in tight spaces. By pairing robust materials with clear labeling and compatibility with PLG accessories, it delivers faster, safer field service and lower lifecycle costs for process plants, chemical facilities, and other demanding sites.

Eaton Specification Sheet - PLG85 SA
Copper-free aluminum construction reduces weight and corrosion potential, improving long-term durability in harsh environments. This translates to lower handling fatigue for technicians and reduced maintenance intervals, delivering measurable lifecycle cost savings in chemical and oil & gas facilities. The 3 inch trade size and 3.5 inch length/height, along with a 2.26 inch width, enable straightforward integration with standard rigid/IMC conduit runs, supporting faster现场 terminations and fewer rework incidents in busy plant environments. Square head design enhances grip and tool engagement, improving installation speed even in confined spaces. Area classification as Hazardous/Classified Locations, together with NEC/CEC standards alignment, ensures compliant installations that satisfy regulatory audits. The copper-free aluminum also provides corrosion resistance without sacrificing strength, aligning with sustainability goals while maintaining mechanical integrity in outdoor or moisture-prone areas. Compatibility with PLG series accessories streamlines procurement and stocking for maintenance teams.

FAQs
For hazardous locations, ensure the conduit plug is used with compatible rigid/IMC fittings and installed per NEC/CEC requirements. Verify Class I, II, and III ratings for your specific environment, and use UL-listed accessories to maintain explosion-proof integrity. The square-head design supports quick grip with standard hand tools, reducing on-site installation time while preserving a tight seal against dust and moisture.
Key specs include copper-free aluminum construction, 3 inch trade size, 3.5 inch length and height, 2.26 inch width, and a square-head design. The product is designed forRigid/IMC conduit and is compatible with the PLG accessory family. UPC 782274101354 helps with fast part identification during procurement and on-site stocking.
Yes. The PLG85 SA is intended for NEC/CEC classified areas, including Class I, II, and III environments. It carries hazardous-location ratings and UL certification for explosion-proof service, supporting compliance in widely used regulatory frameworks and simplifying audits for chemical, oil & gas, and alternative energy facilities.
Copper-free aluminum offers superior corrosion resistance and reduced weight, which translates to easier installation and less wear on mounting hardware. The material choice lowers maintenance cycles, extends component life in harsh environments, and reduces total cost of ownership in outdoor, humid, or chemical plant settings where conduit terminations are exposed to aggressive conditions.
The PLG85 SA is part of the Eaton Crouse-Hinds PLG family, designed to pair with compatible explosion-proof reducers, adapters, and plugs. This compatibility simplifies procurement, inventorying, and field replacement, ensuring consistent performance across a plant’s hazardous-location conduit system and reducing the risk of mismatched components.
