Link-Seal® Modular Seals
Model C (EPDM)
By Pipeline Seal &
Insulator, Inc.

Engineered seals
for sealing pipes
through walls, floors & casings.

| Overview

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 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.
Link-Seal modular seals are also
available for a wide variety of special applications, temperature
extremes, exotic chemical combinations and for “out of round” or
non-centered applications. Please contact Corrosion Control Products
Company for your special application.

Benefits /
Features
- 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 with 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...
Color coded EPDM, Nitrile, & Silicone elastomers may be used with
various hardware options to match performance characteristics with
service conditions.
