Eaton LSA300 FS 05 Link-Seal Environmental Seal - 3h rating
Part Number: LSA300 FS 05
Quick Summary
Eaton LSA300 FS 05 Link-Seal environmental seal provides robust conduit sealing for electrical enclosures in industrial settings. The main challenge is maintaining a leak-free penetration through cast or cored holes and steel sleeves, which often drives costly maintenance and downtime. Certifications listed include Ordinary/Non-Hazardous area classification and a 3 hour rating; note that SIL, CE, or IP ratings are not indicated in the provided data, so verify applicability to your facility standards. With silicone construction and compatibility with EMT, IMC, and RSC conduits, this solution supports long service life, reduces replacement frequency, and improves total cost of ownership for mission-critical installations.

Eaton Specification Sheet - LSA300 FS 05
Feature → Business Impact → Application: Silicone construction delivers excellent temperature tolerance and chemical resistance, translating to lower seal failure rates and fewer field repairs. This reduces maintenance costs and extends service life in harsh plant environments, especially where silicone seals are exposed to oils, solvents, or temperature fluctuations. Application: sealing conduit penetrations in steel sleeves through cast or cored holes in electrical panels.Feature → Business Impact → Application: The 3 hour rating helps maintain integrity during short-term heat or arc events, reducing the risk of leakage and downtime. This enhances reliability in critical enclosures and supports compliance with safety expectations in live installations. Application: temporary or intermittent high-temperature exposure scenarios within ordinary/Non-Hazardous locations.Feature → Business Impact → Application: EMT, IMC, and RSC conduit compatibility simplifies field installation and eliminates the need for multiple seals. This reduces installation time and training requirements. Application: retrofit or new-build projects using common conduit types in industrial facilities.Feature → Business Impact → Application: Trade sizes of 1-1/4" and 1-1/2" provide flexible sizing for typical field penetrations, limiting inventory variety and simplifying procurement. Application: projects with mixed conduit runs and standard hole sizes.Feature → Business Impact → Application: Used with cast/cored holes and steel sleeves ensures a durable, long-lasting seal resistant to vibration and environmental exposure. This lowers maintenance frequency and supports longer service intervals in harsh environments. Application: panel penetrations in steel enclosures and retrofits where sleeves are present.

FAQs
Installation involves preparing a cast or cored hole with a steel sleeve, selecting the correct trade size (1-1/4" or 1-1/2"), and seating the silicone Link-Seal firmly around the conduit. Ensure the hole surface is clean and the sleeve is properly aligned to prevent binding. The silicone material provides a reliable seal once tightened to the enclosure flange, minimizing leakage paths and reducing installation errors common with less flexible seals.
The unit supports trade sizes of 1-1/4" and 1-1/2" and is designed for cast/cored holes with a steel sleeve. This makes it compatible with EMT, IMC, and RSC conduits, offering flexible retrofits for standard industrial installations while maintaining a compact footprint.
Yes. The product is classified for Ordinary/Non-Hazardous Locations, aligning with common plant environments. Always confirm local code compliance for your specific application and consider the 3 hour rating as a resilience factor during short-term exposure to heat or environmental stress.
The provided data lists Area classification as Ordinary/Non-Hazardous Locations. There is no explicit SIL, CE, or IP rating listed for this model, so verify the exact certifications with Eaton for your facility’s regulatory requirements before deployment.
The silicone formulation and 3 hour rating deliver durable sealing with reduced risk of seepage over time, translating to fewer field repairs and lower maintenance costs. Compatibility with common conduit types and the steel sleeve approach further streamline installation and retrofits, supporting lower total cost of ownership in ongoing electrical enclosure projects.
