The System is the Solution. 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. The sleeve is a cost effective product for the fire stopping of pipe penetrations e.g. Plumbing pipe and metallic pipes whilst maintaining similar thermal and acoustic properties as standard mineral fibre insulation. These properties ensure compliance to water bye laws and building regulations for cold and hot water pipes and heating systems..

Link-Seal Modular Seals can seal pipe penetrations ranging in size from 10mm to 3.6m diameter. Specially formulated to withstand attack from ozone, UV, water, hydrocarbons and a wide range of chemicals, Link-Seals are available in liquid, gas, oil, temperature & fire resistant models. With a wide variety of hardware/ elastomer combinations. Pipe Penetrations have been around for hundreds of years, it is believed that the sealing of pipe penetrations date back to the time of the Vikings. The technique typically used was called “oakum”, where a braided rope was dipped into tar and then wrapped around the object until the annular space was filled. The method worked and was used.
