Sheet Metal  Spiral Pipe & Fittings  Gasketed

Gustafson G-3® is a self-sealing gasketed duct system. A triple-lipped EPDM rubber gasket is placed in a groove at the end of the fitting. When the fitting is inserted into the spiral duct, the gasket folds back forming a seal against the inside of the spiral duct and eliminating the need for any sealer.
