Quick Summary

The Eaton LSA300 T 05 Link-Seal environmental seal is designed to seal conduit entries in enclosures and wall openings with reliability. Engineers often struggle with leaks, installation variability, and space constraints when adding penetrations through cast or cored holes. The product aligns with ordinary/non-hazardous area classifications and uses a silicone elastomer to deliver durable sealing while supporting EMT, IMC, and RSC conduits. This combination helps reduce field rework, speeds up installation, and enhances long-term system integrity for commercial and industrial electrical installations. By integrating with standard conduit systems, it delivers measurable business value through lower maintenance costs and consistent performance.

Feature → Business Impact → Application: Silicone material provides resilient environmental sealing that resists weathering and chemical exposure, reducing leakage risk and extending service life in conduit penetrations across industrial facilities. This translates to lower maintenance costs and fewer retrofit surprises when adding or upgrading conduit seals in existing installations. Application: Use with cast or cored holes and a steel sleeve to create a reliable seal for EMT, IMC, and RSC conduits in ordinary locations, streamlining retrofits and new builds alike. Feature → Business Impact → Application: Trade-size options of 1-1/4" and 1-1/2" align with common conduit penetrations, enabling rapid selection without field cutting or custom solutions, which cuts project lead times. Application: Ideal for control panels, equipment rooms, and service entry points where space is at a premium and precision fit is critical. Feature → Business Impact → Application: Product dimensions (6.63 in length, 4.5 in height, 5.13 in width) and a compact 1 lb weight support easy handling and planning, reducing on-site install time and inventory footprint. Application: Fits standard installation envelopes in panel doors and wall penetrations, enabling predictable procurement and consistent performance.

FAQs

Installation steps follow Eaton’s IF 1374 guidelines and the accompanying installation sheets. Begin by preparing a cast or cored hole with a steel sleeve, insert the LSA300 T 05 seal, and verify seating and compression around the conduit to maintain the integrity of the seal. This process minimizes leakage paths and ensures a robust environmental barrier.
The LSA300 T 05 supports trade sizes of 1-1/4" and 1-1/2" and is designed for use with cast/cored holes and steel sleeves. It accommodates EMT, IMC, and RSC conduit types, simplifying specification when planning penetrations for power distribution and control systems.
This environmental seal is specified for Ordinary/Non-Hazardous Locations, aligning with common industrial and commercial installations. It provides a reliable barrier against dust and moisture in typical workplace environments while avoiding over-engineered solutions for non-hazardous settings.
Access the Crouse-Hinds Link-Seal catalog page for overview information, the IF 1374 installation instructions for step-by-step guidance, and the Eaton specification sheet for detailed technical data. These documents support compliant selection, installation, and warranty considerations.
Key benefits include silicone durability for long service life, compatibility with EMT/IMC/RSC conduits, and precise sizing (1-1/4" and 1-1/2") to minimize leakage and field adjustments. The solution also reduces installation time and maintenance costs by providing a proven, standard-compatible seal for cast/cored penetrations.
