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 ensures exceptional durability in damp environments, providing reliable sealing against moisture, groundwater, and organic chemicals for pipelines and direct burial applications.
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. Use our convenient LINK-SEAL® Calculator to view the number of links needed for your project.
Features and Benefits
- Install in up to 75% less time compared to lead-oakum joints, hand-fitted flashings, mastics, or caulk.
- 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 resistance is 50-times greater than standard zinc plating for maximum corrosion protection.
- NSF 61 and Factory Mutual Fire Approved materials available. Also carry a wide variety of approvals from other various agencies, including Lloyd's Register, government 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 a wide range of pipe diameters and service conditions.
