LINK-SEAL Modular Seals
LINK-SEAL Modular Seals are considered to be the premier method for permanently sealing pipes passing through walls, floors and ceilings. Any cylindric object may be quickly, easily, and permanently sealed, as they pass through barriers.
LINK-SEAL Modular Seals serve the following Industries:
- Water and Wastewater
- Mining
- Oil and Gas
- Marine
- Power Generation
- Primary Metals
- Pulp and Paper
LINK-SEAL Modular Seals have the following Features and Benefits:
- Install in up to 75% less time compared to traditional sealing methods.
- Rated at 20 psig (40ft of head), which exceeds the performance requirements of most applications.
- The modular system can be configured to suit any pipe diameter.
- 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 certification for use in Potable Water applications.
- Factory Mutual Fire Approved materials available for use in the Oil & Gas industries.
- Certified for Marine application and carries 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.
LINK-SEAL Modular Seals have the following specifications.
- Pressure resistant to 20psig (40 ft of head)
- For standard applications, use EPDM rubber (black)
- For oil resistance, use Nitrile rubber (green)
- For temperature resistance, use Silicone rubber (gray)
- For fragile pipe, use low durometer EPDM rubber (blue) Shore-A 40 ± 5
Hardware Options – S316 Stainless Steel and Zinc Dichromate Coated Steel (1470 hr salt spray tested) hardware
