Crouse-Hinds LSA300-C EPDM Link-Seal Environmental Conduit Seal

Crouse-Hinds LSA300-C EPDM Link-Seal Environmental Conduit Seal

The Crouse-Hinds LSA300-C is an EPDM environmental conduit seal, commonly known as a link-seal, engineered to create a watertight and dust-tight barrier around conduit runs where they pass through walls, floors, foundations, or sleeves. Built with durable EPDM sealing elements, this conduit seal helps electrical contractors and facility teams keep moisture, gases, and debris from migrating along the conduit path into a building or enclosure. The interlocking link design compresses around the conduit as it is tightened, forming an adjustable mechanical seal suited to a range of penetration conditions. As a Crouse-Hinds product, the LSA300-C is designed to deliver dependable, code-conscious sealing performance for conduit penetrations in commercial, industrial, and utility environments.

Key Features

• EPDM Construction: The sealing links are manufactured from EPDM, a synthetic rubber compound valued for its resistance to weathering, ozone, and a wide range of environmental conditions, helping the seal maintain integrity over time.
• Environmental Conduit Seal: Designed specifically to seal the annular space between a conduit and the wall or sleeve opening it passes through, reducing the pathway for water, gas, and pest intrusion.
• Link-Seal Style Design: Uses an interlocking link configuration that compresses around the conduit as it is tightened, forming a mechanical, adjustable seal suited to a range of penetration conditions.
• Crouse-Hinds Build Quality: Manufactured under the Crouse-Hinds brand, a name long associated with rugged, application-focused electrical sealing and conduit products for demanding installations.
• Conduit Application: Intended for use with conduit systems where a reliable environmental barrier is required at the point of wall or foundation penetration.
• Adjustable Sealing Elements: The link-based construction allows the seal to be tightened to conform to the specific conduit and sleeve dimensions on site, giving installers a practical field-fit solution.
