Paragraph 1: Feature: 3 inch trade-size silicone environmental seal with a 3-hour rating. Business Impact: provides a robust, watertight barrier for standard conduit openings, dramatically reducing moisture and dust ingress that can compromise electronics. Application: ideal for EMT, RSC, and IMC penetrations in electrical enclosures across manufacturing plants and control rooms. Paragraph 2: Feature: Cast/cored hole compatibility with a steel sleeve. Business Impact: enables straightforward retrofits and new installations without custom metalwork, shortening commissioning and minimizing field adjustments. Application: retrofit projects in existing panels or new builds where standard cast/cored holes are used. Paragraph 3: Feature: Silicone material with proven chemical and temperature stability. Business Impact: maintains seal integrity under varying plant temperatures and exposure to oils, solvents, or humidity, improving long-term reliability. Application: control panels, switchgear, and enclosures in non-hazardous locations. Paragraph 4: Feature: Emphasis on standard sizes and documentation. Business Impact: easy selection and installation thanks to catalog pages, installation instructions, and spec sheets, reducing design risk and training time. Application: procurement workflows and commissioning checklists for electrical contractors. Paragraph 5: Feature: Compacted form and documented dimensions. Business Impact: 5.75 in length/depth, 8 in height, 4.55 lb weight; enables one-person handling and simpler logistics.

FAQs

The LSA300 FS 08 supports EMT, RSC, and IMC conduits and is installed by preparing a cast/cored hole sized for the 3 inch seal, inserting the Link-Seal with a steel sleeve, and following the installation instructions IF 1374. The silicone seal maintains a watertight barrier across temperature ranges and exposure to moisture, dust, and oils.
The unit uses silicone as the seal material and carries a 3-hour rating for environmental sealing. It is designed for a 3 inch trade size and is compatible with EMT, RSC, and IMC conduits, making it suitable for standard panel penetrations in non-hazardous settings.
No. The product is rated for Ordinary/Non-Hazardous Locations, which means it is not specified for hazardous or classified locations. For such environments, review alternative seals that meet applicable safety standards.
Eaton provides a catalog page for the Link-Seal family, installation sheets (IF 1374), and a dedicated specification sheet for the LSA300 FS 08. These documents support correct sizing, hole preparation, and step-by-step installation guidance to minimize commissioning time.
The seal offers reliable ingress protection for non-hazardous locations, reduces field rework and maintenance costs, and shortens commissioning time due to clear documentation. It also supports standard conduit entries, which lowers retrofit risk and improves overall panel reliability in manufacturing environments.
