FAQs
LSA300 C 04 supports EMT, IMC, and RSC conduits with trade sizes of 1 inch and 1-1/4 inch. It is designed for use with cast or coring holes and plastic sleeves, enabling straightforward retrofits across common electrical installations. This compatibility reduces stocking complexity and speeds up field installations while maintaining a reliable seal.
The EPDM sealing element compresses around the conduit entry, forming a tight, resilient barrier against moisture, dust, and contaminants. The carbon steel/zinc housing provides structural integrity and corrosion resistance, ensuring seal performance across typical factory temperatures. Together, these features minimize ingress paths and extend service life in conduit penetrations.
Yes. The LSA300 C 04 is certified for ordinary/non-hazardous locations, making it suitable for general manufacturing floors, warehouses, and process areas. Its versatility with EMT, IMC, and RSC conduits, plus its compatibility with cast/cored holes and plastic sleeves, supports a wide range of standard industrial applications without specialized certifications.
The product is rated for Ordinary/Non-Hazardous Locations, aligning with typical industrial environments. This classification helps ensure regulatory compliance for standard manufacturing and distribution facilities. Always verify local electrical codes and installation guidelines, and consult the IF 1374 installation sheet for correct seal usage.
Using LSA300 C 04 reduces downtime by delivering a durable, site-proven seal that minimizes ingress, reduces sealing failures, and lowers maintenance cycles. Standardized conduit compatibility across EMT, IMC, and RSC simplifies procurement and field training, while official catalogs, installation instructions, and datasheets streamline correct installation, accelerating project timelines and delivering predictable lifecycle costs.
