Link-seal ls-615-c Modular Pipe Seal Size 615 Epdm

Product Description

The LINK-SEAL ls-615-c is a modular elastomeric pipe sealing system designed to create a permanent, hydrostatic seal around pipes and cylindrical objects as they pass through barriers such as concrete walls, floors, and foundations. This Size 615 unit uses a black EPDM rubber seal element with a durometer rating of 50, a reinforced nylon polymer pressure plate, and zinc plated carbon steel hardware. The assembly compresses the EPDM links radially around the pipe annular space, closing off the penetration against groundwater, moisture, and organic chemical intrusion. Licensed plumbers, pipefitters, and civil contractors install this system in both new construction and retrofit applications.

The ls-615-c Model C is suited for pipelines and direct burial applications where damp environments and groundwater exposure are primary concerns. EPDM performs reliably across a temperature range of -40 degrees F to 250 degrees F, making it appropriate for cold-climate underground utility work as well as moderate-temperature fluid systems. Where greater water contact is anticipated, the Model S316 with stainless steel hardware is the recommended step-up. For applications involving elevated chemical exposure, the Model O with nitrile rubber and stainless steel hardware is the appropriate alternative.

Key Features

• Black EPDM rubber seal element rated for -40 degrees F to 250 degrees F continuous service
• Durometer 50 for consistent compression and positive annular contact around the pipe
• Reinforced nylon polymer pressure plate distributes bolt load evenly across seal links
• Zinc plated carbon steel hardware provides corrosion resistance in damp, below-grade environments
• Modular link construction accommodates a wide range of pipe outside diameters at Size 615
• Provides a permanent hydrostatic seal against groundwater, moisture, and organic chemicals

Compatibility

Designed for use at pipe wall penetrations through concrete barriers in pipelines and direct burial applications. For increased water contact, Model S316 with black EPDM and stainless steel hardware is recommended. For increased chemical contact, Model O with nitrile rubber and stainless steel hardware is recommended.

Installation Notes

Installation is typically performed by licensed plumbers, pipefitters, or civil contractors following applicable IPC or project-specific specifications. Power down or depressurize any active line before working at the penetration point. Bolts should be tightened in an alternating pattern to achieve even compression across all seal links — consult the LINK-SEAL installation guide for the correct tightening sequence; do not rely on feel alone. Verify the annular space is clean and free of debris before seating the assembly.
