LINK-SEAL® is the original modular, elastomer sealing system that creates a permanent, hydrostatic seal for nearly any pipe or cylindrical object as it passes through a barrier, like concrete walls, providing superior durability and peace of mind against fluid corrosion and contamination.


LINK-SEAL® Model C with Black EPDM and Carbon Steel Hardware offers unparalleled longevity in damp environments, featuring a corrosion-inhibiting organic coating and proprietary zinc formula that outperforms competitors, proven by a 1,470-hour salt spray test, ensuring robust sealing against occasional groundwater, moisture, and organic chemicals in direct burial and pipelines.


For increased water contact, consider Model S316 with Black EPDM and Stainless-Steel Hardware, and for increased chemical contact consider Model O with Nitrile Rubber and Stainless-Steel Hardware.


  • Overview

Features and Benefits:

  • Install in up to 75% less time compared to lead-oakum joints, hand-fitted flashings, mastics, or casing boots.
  • Rated at 20 psig (40ft of head), which exceeds the performance requirements of most applications.
  • Designed for use as a permanent seal. Seal elements are specially compounded to resist aging and attack from ozone, sunlight, water, and a wide range of chemicals.
  • Standard fasteners have a two-part zinc dichromate and proprietary corrosion inhibiting coating. Corrosion resistant 316 stainless steel available for maximum corrosion protection.
  • NSF 61 and Factory Mutual Fire Approved materials available. Also carry a wide variety of approvals from various Federal agencies, associations, code groups, laboratories, and organizations.
  • Manufactured in an ISO 9001 certified facility.
  • 16 sizes, color-coded EPDM, Nitrile, and Silicone elastomers may be used with various hardware options to match performance characteristics with service conditions.
