Link-Seal Saves Time and Money Link-Seal installs in up to 75% less time compared to lead-oakum joints, hand-tilted flashings, mastics, or casing boots. That means important cost savings. Positive Hydrostatic Sealing Properly installed, Link-Seal is rated at 20 psig (40 feet of head), which exceeds the performance requirements of most applications. Long Seal Life Link-Seal is designed for use as a permanent  seal. Many installations have been in service for 25 years. Seal elements are specially compounded to resist aging, ozone, sunlight, water and a wide range of chemicals. Seals Any Pipe If it's round, Link-Seal can seal it ! Applications include concrete, cast iron, steel, copper, plastic, electrical and telecommunications cable. Fire Protection For fire protection in floor and wall penetrations the fire-rated version of Link-Seal is Factory Mutual approved. Resistant to Extreme Temperatures Link-Seal is available in special compounds that resist temeratures from as low as -60F to as high as 400 F. Corrosion Protection Where insulation against galvanic corrosion (or electrolysis) is required, Link-Seal provides complete separation of pipe and casing. Metal-to-metal contact is eliminated. Compensates for Misalignment Link-Seal allows for some angular and off-center pipe conditions and still seals effectively. Absorbs Shocks, Sound and Vibration This inherent benefit of Link-Seal helps reduce pipe failures due to fatigue, at welds, flanges and threaded connections.
