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.

Crouse-Hinds LSA300-C-06 – Frequently Asked Questions

1) What trade sizes does the Crouse-Hinds LSA300-C conduit seal come in?
Two trade sizes are offered: 2-inch (LSA300-C-06) and 4-inch (LSA300-C-10). Pick the one that matches the conduit trade size running through the penetration, since the links compress around that conduit inside the sleeve or opening.
2) Will a link-seal like the LSA300-C stop water coming through a conduit sleeve in a foundation wall?
That is exactly what it is for. The LSA300-C seals the annular space between the conduit and the wall, floor, foundation, or sleeve opening it passes through, forming a watertight and dust-tight barrier that blocks water, gas, and debris from migrating along the conduit path into the building or enclosure.
3) Is the LSA300-C seal material suitable for outdoor and exposed conduit penetrations?
The sealing links are EPDM, a synthetic rubber chosen for resistance to weathering, ozone, and a wide range of environmental conditions, so it holds up at exposed exterior penetrations as well as interior ones.
4) How does a link-seal install compared to pouring or caulking a conduit penetration?
It is a mechanical seal, not a cured one. The interlocking links wrap the conduit inside the sleeve and compress as the bolts are tightened, so the seal conforms to the actual conduit and sleeve dimensions on site. Nothing has to cure, and the assembly can be loosened and re-tightened, which makes it workable on retrofit penetrations as well as new construction.
5) Can I standardize on one seal type across a facility's conduit penetrations?
Yes. Crouse-Hinds LSA300-C seals are an environmental conduit seal line intended for wall, floor, and foundation penetrations across commercial, industrial, and utility installations, so a facility or MRO team can spec a single brand and style at every conduit entry and just order by trade size, 2-inch or 4-inch.
6) Does the LSA300-C seal also keep pests and gas out, or just water?
Both. By closing the annular space around the conduit it reduces the pathway for water, gas, and pest intrusion, which is why it gets used where a conduit run enters an occupied building or an enclosure.
