Feature → Business Impact → Application: The LSA275 C 07 uses EPDM material in contact with carbon steel/zinc hardware, delivering a durable, non-corrosive seal that resists weathering and chemicals in typical plant environments. This translates to extended service life and reduced maintenance expenses for conduit penetrations in IMC and RSC systems. Application-wise, it seals 1-1/4" trade-size conduits used in cast or bored holes, enabling rapid installation in a wide range of assemblies without specialized fittings. Another feature is the compact 4.5" length with a 3.13" height and 3.88" width, which fits tight penetrations while maintaining reliable compression. The product is designed for Ordinary/Non-Hazardous Locations, ensuring regulatory compatibility in standard manufacturing floors and electrical rooms. Installation instructions and datasheets support quick onboarding and consistent field practices.

FAQs
Installation involves preparing the cast or cored hole to the specified diameter, inserting the LSA275 C 07 assembly, and ensuring any sealing surfaces are clean and free of debris. Follow the IF 1374 installation sheet for step by step guidance, use compatible IMC or RSC conduit, and verify the sealing fit with the assigned gapping and compression requirements to achieve optimal ingress protection.
Yes. The LSA275 C 07 is designed for IMC and RSC conduit types, enabling a secure fit in cast or cored holes. This compatibility simplifies procurement and installation by reducing the need for multiple seal types, while maintaining a consistent sealing interface across common conduit standards in industrial facilities.
This seal is suitable for Ordinary/Non-Hazardous Locations, aligning with standard manufacturing floors and electrical rooms. While weather and exposure resistance are driven by EPDM, always verify site conditions such as humidity, chemical exposure, and temperature range to ensure compatibility with the seal’s material properties and the surrounding environment.
Key benefits include reliable moisture and environmental sealing for cast or cored holes, compatibility with IMC and RSC conduits, and a compact footprint that suits tight penetrations. These features translate to reduced rework, faster installations, better compliance with electrical codes in ordinary locations, and lower lifecycle costs through fewer maintenance interventions.
