Eaton LSA300 T 10 Link-Seal Environmental Seal - Silicone
Part Number: LSA300 T 10
Quick Summary
The Eaton LSA300 T 10 Link-Seal environmental seal protects conduit penetrations in steel sleeves for durable, weather-resistant electrical enclosures. Field installations often struggle with leaks at conduit penetrations, leading to downtime and maintenance costs. This product is specified for ordinary/non-hazardous locations, with silicone material delivering chemical resistance and long service life. Designed to simplify procurement and installation, it supports EMT, RSC and IMC conduits while meeting space and compatibility needs in industrial facilities. The combination of a 4 inch trade size and a compact form factor helps installers reduce field time and inventory complexity. Using this seal can lower leak paths, improve reliability, and support maintenance budgets by reducing unplanned outages.
