In commercial construction, industrial plants, municipal infrastructure, data centers, and virtually any project where piping penetrates walls and floors, the quality of your sealing system matters.
That’s where LINK-SEAL® modular pipe sealing systems come in—and why sourcing them from Maddock Industries is a smart choice for engineers, contractors, and building owners alike.
What Is LINK-SEAL?
LINK-SEAL is a modular elastomer sealing system designed to create a permanent, hydrostatic seal around pipes, conduits, and other cylindrical penetrations through walls, floors, and ceilings. Instead of relying on grout, caulk, or improvised solutions, LINK-SEAL uses interlocking rubber links that compress evenly around the pipe, forming a reliable, gas- and water-tight seal.
Proven Performance You Can Rely On
LINK-SEAL systems are engineered for demanding environments. The modular elastomer links expand under compression to deliver consistent sealing pressure, while hardware options (including corrosion-resistant stainless steel) ensure durability in harsh or corrosive conditions.
Another major advantage is installation efficiency. LINK-SEAL systems can be installed significantly faster than traditional sealing methods, helping reduce labor time, minimize rework, and keep projects moving on schedule.
Versatile Solutions Across Industries
LINK-SEAL systems are used across a wide range of applications, including HVAC and chiller piping, fire protection systems, utility vaults, parking structures, and foundation penetrations. Their flexibility, durability, and long-term reliability make them an ideal choice wherever water, gas, or debris intrusion must be prevented.
With proper material selection, LINK-SEAL systems deliver dependable performance with minimal maintenance over time.
