Eaton Specification Sheet - ES65 SG
Dual hub geometry provides immediate compatibility with common conduit sizes. This reduces field modification and eliminates the need for adapters, lowering inventory costs. Ideal for industrial installations in hazardous locations where tight seals and quick assembly matter. Feraloy iron alloy body offers high strength and corrosion resistance. Extends service life in challenging environments common to refineries, chemical plants, and offshore facilities. Suitable for explosion-proof conduit fittings in Class I, Division 1/2 environments, meeting demanding maintenance cycles. Integrated sealing gasket and locknut deliver a reliable environmental seal. Improves gasket integrity, reduces leak paths, and lowers commissioning risk. Ensures consistent IP/UL rated assemblies in enclosures and conduits, even with thermal cycling. NEC/CEC compliance and Class I Division 1/2 ratings provide regulatory alignment. Simplifies code approvals and site acceptances, reducing engineering hours. Fits standard hazardous-location projects with UL Canada certifications (per UL reports). Precise dimensions and weight facilitate predictable fit and easy handling in tight spaces. 2.75 in length/depth, 3.06 in height, 2.75 in width, and 1.8 lb weight enable efficient field replacements. Accelerates start-up with documented procedures and recommended practices via IF 1728 installation guidance. Refer to Eaton’s IF 1728 sheet and data sheets for on-site guidance. Catalog and data sheet availability improves sourcing accuracy and due diligence. Use alongside installation docs for compliant assemblies in hazardous locations. Broad industry applicability across oil & gas, chemical processing, power distribution, and industrial automation reduces total cost of ownership by minimizing downtime and boosting reliability.
