Eaton LSA300 FS 06 Link-Seal Environmental Seal - 3h Rating
Part Number: LSA300 FS 06
Quick Summary
Link-Seal environmental seal provides reliable conduit sealing for electrical enclosures in tough industrial environments. Engineers often confront leaks, dust intrusion, and rework around penetrations, leading to downtime and escalating maintenance costs. This Eaton solution carries area classification for Ordinary/Non-Hazardous Locations and leverages a durable silicone body with a 3-hour rating, delivering dependable performance under demanding conditions. By optimizing for IMC and RSC conduits in a 2-inch trade size, this seal reduces installation complexity and helps protect equipment across harsh sites, improving uptime and safety. In practice, replacing seal failures with Link-Seal can reduce service calls and extend enclosure life, aligning with reliability-centered maintenance goals.

Eaton Specification Sheet - LSA300 FS 06
Silicone construction delivers excellent environmental resistance, maintaining seal integrity against dust, moisture, and minor chemical exposure over time. Business impact: reduced maintenance cycles and fewer enclosure breaches, translating to lower total cost of ownership for panel assemblies. Application: ideal for outdoor or harsh indoor environments where enclosure protection is critical and downtime must be minimized. 2 inch trade size with IMC and RSC conduit compatibility simplifies sourcing and installation, eliminating the need for adapters and complex field modifications. Business impact: faster commissioning, lower labor costs, and more predictable project timelines. Application: suitable for standard electrical rooms and outdoor-rated panels that use common conduit types in mid-size facilities. 3 hour rating adds a robust layer of fire-resistance performance to the seal, helping maintain enclosure integrity during transient heat exposures. Business impact: enhanced safety margins and potential compliance alignment for fire-related enclosure protection. Application: relevant to risk-managed facilities seeking reliable seals for critical penetrations. Used with cast/cored holes and steel sleeves, the LSA300 FS 06 delivers a precise, mechanical fit that resists movement and leakage under vibration or panel flexing. Business impact: reduced seal displacement, fewer gasket replacements, and longer service life. Application: ideal for steel enclosures and retrofit projects where a precise bore and sleeve are present. Area classification Ordinary/Non-Hazardous Locations ensures the product is appropriate for standard industrial settings without hazardous atmospheres, supporting straightforward regulatory alignment. Business impact: simpler procurement and fewer compliance hurdles. Application: common in data centers, manufacturing lines, and control rooms where routine enclosure protection is required.

FAQs
Begin by verifying a 2-inch bore for IMC or RSC conduits and prepare a steel sleeve for a clean bore. Follow Eaton's IF 1374 instruction sheet to assemble the LSA300 FS 06 components, insert the seal around the conduit, and seat it evenly in the bore. After installation, perform a leak test per standard enclosure practices to confirm seal integrity.
The 3-hour rating indicates the seal’s validated performance under specified fire-exposure conditions, contributing to maintained enclosure integrity during transient heat events when used as part of the approved assembly. It reflects the seal’s resilience within the recommended enclosure system and installation practices.
Yes. The product is classified for Ordinary/Non-Hazardous Locations and is designed for cast/cored holes with a steel sleeve. Its silicone construction offers suitable resistance for typical industrial environments, making it appropriate for standard panels, control rooms, and similar applications without hazardous atmospheres.
The silicone Link-Seal provides durable, long-term sealing with reduced leak points around penetrations, lowering maintenance calls related to ingress. Its compatibility with common conduit types and clear installation guidance helps ensure consistent performance, translating to lower lifecycle costs and improved reliability of electrical enclosures.
Verify the conduit type (IMC or RSC), the 2" trade size, and the presence of a suitable steel sleeve for the cast/cored hole. Ensure the enclosure location matches the Ordinary/Non-Hazardous classification and review Eaton's installation instructions (IF 1374) for correct assembly and testing to ensure proper sealing.
