FAQs
Installers should verify vertical or horizontal sealing compatibility, use the correct 2-1/2" trade-size mating components, and follow the IF 287 installation instructions. The fitting is designed for Class I, II, and III locations and requires compliant mounting practices to maintain UL and NEC/CEC certifications. Field orientation and secure mounting reduce ingress risks and project rework.
The EYS7 meets NEC/CEC standards and has NEC hazardous ratings including Class I, Division 1 and 2, Class II, Division 1 and 2, and Class III. UL certifications for hazardous locations confirm suitability for explosive atmospheres. These credentials matter because they demonstrate regulatory compliance, safer operation, and eligibility for regulated industries such as oil and gas, chemical processing, and mining.
Yes. With its ductile iron construction, hazardous-location ratings (Class I/II/III), vertical or horizontal sealing, and UL/NEC/CEC compliance, the EYS7 is well-suited for oil & gas, chemical processing, and other environments where conduit penetrations must resist moisture, dust, and hazardous atmospheres while maintaining certified performance.
Confirm the trade size (2-1/2"), material (ductile iron with Feraloy alloy), gender (female), and sealing orientation (vertical or horizontal). Also verify dimensions (7.5 in L x 4.5 in H x 3.5 in W) and weight (8.25 lb) to ensure fit and serviceability within your enclosure or gland system, and cross-check NEC/CEC and UL data for compliance.
The rugged ductile iron construction and proven sealing capability reduce ingress-related failures, lowering maintenance downtime and replacement costs. UL and NEC/CEC certifications help minimize compliance risk, while installation guidance and CAD resources shorten commissioning time. Overall, the EYS7 supports safer, longer-lasting service life for critical plant infrastructure.
