Engineered for superior sealing performance, the PGKD Modular Link Seal from American Polywater is designed for applications requiring durability and reliability in pipe and conduit systems. Its integrated visual installation control eliminates the need for a torque wrench, making installation straightforward and efficient. Constructed with high-quality stainless steel V4A (AISI 316L), every component ensures longevity and resistance to environmental factors, while the seal is gastight and watertight up to 72.50 PSI (5 bar). Available in either EPDM or NBR rubber, this modular link seal accommodates a range of carrier pipe diameters from 7.000 inches to 27.992 inches and supports an annular space from 0.945 inches to 1.181 inches. Notably, the design features molded nuts within the pressure plates to avoid loose parts, and the visual installation indicator confirms that the seal is compressed correctly upon installation, requiring no subsequent retightening. This innovative solution addresses the critical need for a secure and reliable seal in industrial environments, bringing peace of mind to any piping project.
