FAQs
EYSX7 SA is designed for vertical or horizontal sealing in hazardous locations and accepts a 2-1/2 in trade-size conduit. For best results, follow the IF 288 installation sheet alongside the Eaton datasheet to ensure correct gland torque, sealing compound, and enclosure clearance. The copper-free aluminum construction reduces weight while maintaining rugged protection, aiding field teams during multiple shifts.
Key specs include female gender, 2-1/2 in trade size, copper-free aluminum material, 4.75 in length, 9.19 in height, 4.75 in width, and a weight of 6.95 lb. It supports Hazardous/Classified Locations per NEC/CEC and Class I, II, and III ratings, with vertical or horizontal sealing orientations for flexible installation.
Yes. The 2-1/2 in trade size matches common conduit fittings, and the female connection aligns with standard conduit seals used in industrial installations. Copper-free aluminum reduces weight, improving handling. For reliability, reference the EYSX7 SA datasheet and installation guide to verify seal type, gasket compatibility, and mounting hardware requirements.
EYSX7 SA carries NEC/CEC standards and UL certifications for use in hazardous locations. The product is rated for Class I, Division 1 and 2, Class II, Division 1 and 2, and Class III environments, with area classifications for Hazardous/Classified Locations. This combination supports compliance across oil & gas, chemical processing, and mining facilities.
The expanded fill design reduces seal failures and leakage risk, potentially lowering downtime and maintenance costs. Copper-free aluminum lowers weight for quicker field installation, while compliance with NEC/CEC and UL certifications accelerates approvals. Access to installation sheets and datasheets also minimizes field questions, improving project timelines and long-term reliability.
