With Fuseal Squared™, GF Piping Systems offers a double containment piping system for the disposal of special waste. Depending on the application, the system is available in a flame-retardant or a non-flame-retardant version (PPFR and PPNFR). The standard wall thickness makes Fuseal Squared™ ideal for underground applications. Thanks to simple connection procedures, the pipes are easy to join during installation.
