Eaton Crouse-Hinds PLG28 SA conduit plug - Classified

Copper-free aluminum construction delivers corrosion resistance and easier handling, while eliminating copper trace concerns in conduit fittings. That translates to longer service life in harsh industrial environments and lower maintenance costs, as crews spend less time replacing fittings. In practice, technicians appreciate the predictable torque and reliable enclosure sealing that the copper-free material enables in hazardous-location installations. The recessed profile keeps the plug flush with mounting surfaces, reducing snag hazards and ensuring a solid gasket seat. This design minimizes ingress paths at panel openings and improves overall enclosure integrity in demanding applications where vibration and dust are constant challenges. Additionally, the recessed geometry supports faster, more consistent sealing during field service, reducing resealing errors. With a 1/4 inch trade size, the PLG28 SA fits standard small-diameter conduits, while compatibility with rigid/IMC conduit streamlines integration across machines. This combination speeds installation, reduces field modifications, and simplifies spare-part inventory for maintenance teams, translating to lower labor hours per conduit run. Engineers also benefit from standardized dimensions that align with common enclosure templates, supporting faster quoting and more predictable project planning. NEC/CEC compliance plus NEC hazardous ratings Class I Division 1 and 2, Class II Division 1 and 2, and Class III provide regulatory alignment for global projects. UL certification support reinforces quality assurance during audits and helps meet customer procurement requirements. Together these standards reduce compliance risk, simplify supplier qualification, and support safer system startups across industries such as chemical, oil and gas, and manufacturing. Industrial teams benefit from a compact form factor and clear specifications that aid accurate quoting and stock planning. The PLG28 SA’s lightweight profile eases installation overhead on crowded panels, while its 1/4 inch trade size ensures compatibility with widely used conduits. This combination reduces procurement friction and minimizes on-site waste by enabling a single part to serve multiple lines. Engineers also benefit from standardized dimensions that align with common enclosure templates, supporting faster quoting and more predictable project planning. The recessed plug design minimizes snag hazards and supports reliable sealing in vibration-prone environments, delivering measurable gains in uptime.
