Link-Seal® Modular Seals
Link-Seal® modular seals are considered to be the premier method for permanently sealing pipes of any size passing through walls, floors and ceilings. In fact, any cylindrical object may be quickly, easily and permanently sealed, as they pass through barriers, by the patented Link-Seal® modular seal design.
Ductile iron, concrete, metal as well as plastic pipes may be hydrostatically sealed within walls to hold up to 20 psig (40 feet of static head). Electrical or telecommunications cable may be sealed within conduit as they enter vaults or manholes. The annular space between carrier pipes passing through casings may be sealed against the entry of water, soil or backfill material.
With a wide variety of hardware/elastomer combinations, Link-Seal modular seals are easily configured to achieve the best possible match for service conditions encountered. High temperature seals, fire seals (Factory Mutual Approved) and oil resistant seals may be ordered to meet special or unique service applications. For the system approach, metal or non-conductive Century-Line® sleeves with water stops may be ordered with Link-Seal modular seals to ensure correct positioning and a water tight seal of the installation within poured concrete walls.
Link-Seal modular seals are also available for a wide variety of special applications, temperature extremes and exotic chemical combinations.

Saves time and money...
Link-Seal modular seals install in up to 75% less time compared to lead-oakum joints, hand fitted flashings, mastics or casing boots.
Positive hydrostatic seal...
Link-Seal modular seals are rated at 20 psig (40 feet of head), which exceeds the performance requirements of most applications.
Long seal life...
Link-Seal modular seals are 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.
Maximum protection against corrosion...
Standard fasteners have a two-part zinc dichromate and proprietary corrosion inhibiting coating. Corrosion resistant 316 stainless steel available for maximum corrosion protection.
Certification/Approvals...
Factory Mutual Fire Approvals.
Also a wide variety of approvals from various Federal agencies, associations, code groups, laboratories and organizations.
ISO Quality Assurance...
Link-Seal modular seals are manufactured in an ISO 9001:2000 certified facility.
Configure a Link-Seal modular seal to match your application...
16 sizes, color coded EPDM, Nitrile, & Silicone elastomers may be used with various hardware options to match performance characteristics with service conditions.

Century-Line® Sleeves
Century-Line® Pipe Penetration Sleeves are used to create circular sleeved holes in concrete poured barriers including; walls, floors, ceilings, structural supports and tank footings. Molded from non-conductive, high impact resistant HDPE, Century-Line® sleeves are lightweight and easily installed by one construction worker. They are available in 16 diameters ranging from 2" to 25" and shipped, from stock, in any desired length.
Century-line® sleeves are engineered to mate with Link-Seal® modular mechanical seals for a lifetime of leak-proof performance. PSI/Thunderline?Link-Seal® is your one-stop source for everything you need to effectively seal the annular space between pipes and concrete barriers through which they pass.

16 sizes - 2" to 25" in diameter - Local stock, drop ship overnight...
In the event of a field or engineering change, sleeves may be cut shorter at the job site using ordinary hand tools. Standard sleeves are 16" (406mm) in length. Longer length models may also be quickly fabricated as a custom ordered item.
1/8 the weight of steel...
Century-Line® sleeves are light enough for one worker to install without a crane, hoist or helper which reduces installation time and costs. Century-Line® sleeves are easy to stock and store and far less expensive to ship, when compared to steel sleeves.
Resists water migration...
The 2” (50.8mm) water stop collar not only anchors the sleeve in position but creates a long tortuous path against the migration of water around the outside of the sleeve.
Used for shotcrete wall applications...
For shotcrete applications, Century-Line® Sleeves are easily positioned to wall form with threaded rod, and the end caps protect the sleeve penetration while the wall is formed.Z
Adjusts to wall thickness...
Century-Line® sleeves unique hollow water stop collar acts like an expansion joint, adjusting (up to 1/2” - 12.7mm) to the thickness of the wall. This compressive force reacts against the forms like a spring, creating a prevailing tension which maintains proper sleeve location within the form.
Nailer end caps position sleeve precisely in form...
Specially designed end caps provide an ideal method for attaching Century-Line sleeves to the concrete forms. The end caps assure that the sleeve holds its circular configuration during the pour. In addition to keeping out wet concrete, they also prevent dirt from entering the sleeve during backfill operations or the interim construction period.
Tough high density polyethylene (HDPE) construction...
High impact-resistant HDPE also provides excellent resistance to acids, alkalis and other organic solvents. Ideal for cathodic protection systems, these non-conductive sleeves will neither rust, corrode or degrade. Low-temperature properties are such that they may be installed under any weather conditions suitable for pouring concrete. High termperature application limit is 150º F. (66º C.). The sleeve is molded with a texture on the outside surface to assure a better bond, than most other plastics, to concrete interfaces.

PSI / Pikotek Model "C" Coated Metallic Casing Spacers
An extremely tough and durable heat fused fluid bed thermo set cross-linked polymer coating is offered on steel casing spacers/isolators 4" and larger, with 8" and 12" band widths. The cold formed steel casing spacer/isolator band (risers where applicable) and studs for runner mounting
are grit blasted, heated and fusion coated with a cross-linked epoxy polymer formulation, providing a minimum 0.010 (0.254mm) thick coating over the entire metallic surface. A post cured cycle strengthens the bond and provides an even more uniform coating.
Other heat fused formulations are also available for custom orders and applications.
The runners are attached with 3/8" diameter studs, which are fusion welded to the band before it is powder coated. They are recessed far below the wearing surface of the runner. After the runner is anchored to the band, the stud counter-bore is filled with specially formulated caulk to assure a water tight seal for the stud and the locking fastener.
