What Are LINK-SEALS?

Considered to be the premier method for permanently sealing pipes of any size passing through walls, floors and ceilings, LINK-SEALS® are a modular, elastomer sealing system that creates a permanent, hydrostatic seal for nearly any cylindrical object as it passes through a barrier. With LINK-SEALS®, any cylindrical object may be quickly, easily and permanently sealed against the entry of water, soil or backfill material.

Why You Should Use LINK-SEALS®:

• Install in up to 75% less time compared to lead-oakum joints, hand-fitted flashings, mastics, or casing boots.
• 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.
• Rated at 20 psig (40ft of head), which exceeds the performance requirements of most applications.
• 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.
• Standard fasteners have a two-part zinc dichromate and proprietary corrosion inhibiting
  
  coating. Corrosion resistant 316 stainless steel available for maximum corrosion protection.
• Manufactured in an ISO 9001certified facility.
• 16 sizes, color-coded EPDM, Nitrile, and Silicone elastomers may be used with various hardware options to match performance characteristics with service conditions.

Using Link-Seal in Combination with Century-Line Sleeves or Cell-Cast Disks for Sealing Pipe Penetrations when Pouring Walls, Floors or Ceilings

Sealing pipes passing through concrete barriers can be one of the really tough challenges confronted by designers and installers of any piping system. But there's a way to simplify the whole process. All it takes is the system approach.  Link-Seal in combination with Century Line sleeves makes for a dynamic combination.  Just what you need to quickly and easily seal any cylindrical object passing through concrete poured walls, floors, and ceilings.

Link-Seal is a flexible belt of interconnected rubber links used to seal the void area or annular space between a cylindrical pipe and round wall opening. Be it a steel sleeve, plastic sleeve, or poured hole, installation is easy. The belt is simply wrapped around the pipe connected and secured by tightening the bolt heads moving clockwise around the seal. Pressure plates on each side of the link applied the compression necessary to expand the rubber. As the bolts are tightened, the links enlarge from a free to an expanded state, transforming the belt of separate links into a hydrostatic seal capable of holding in excess of 20 PSIG with a safety factor of 5 to 1. In the laboratory under controlled conditions, Link-Seal has been successfully tested to 100 PSIG and above.  In addition, accelerated aging tests have shown Link-Seal to be capable of providing maintenance-free service over performance life cycles estimated at 40 years or more.

In the real world, Link-Seal improves overall system reliability by effectively dampening the damaging effects of vibration.  Link-Seals reduce fatigue on pipe welds, flanges and threaded connections. As an added bonus, they may also be used to isolate stray electric current passing through pipes and casings. Applications for Link-Seal are almost infinite. In fact, any cylindrical object may be quickly easily and permanently sealed as they pass through barriers of all kinds.
