ABC’s RigiDuct® is filament-wound fiberglass tubing designed for proper ventilation. The tubing has excellent strength under high degrees of negative pressure and is highly resistant to attack from acid or alkaline conditions. Our UV-stabilized rubberized elastic gaskets resist degrading and remain pliable in cold weather.
*RigiDuct® is approved by the U.S. Mine Safety and Health Administration (MSHA).
