Nordfab Ducting

Quick-Fit Clamp with Pin

Nordfab manufactures ducting for use in dust, mist, and fume collection systems.

The key component in Nordfab's Quick-Fit® clamp-together ducting system is the easy-to-use Quick-Fit Clamp. The Clamp allows quick connections for Nordfab’s Quick-Fit (QF®) modular ductwork. Quick-Fit Ducting is ideal for dust collection and process ventilation systems, saving time and money on installation, future relocations, and cleanouts. Quick-Fit is also adaptable to existing ductwork.

Silicone and ePTFE are optional seal materials for applications where temperature is not suitable for nitrile. View the guide on our website for selecting the best seal material for your application.

Clamps come standard from Nordfab with Nitrile seals and bridge pin for locking clamp into closed position. Galvanized clamps supplied with galvanized bridge pin. 304SS clamps supplied with SS bridge pin. 3″ to 6″ Clamps: Small bridge pin with 3/8″ wide Nitrile seal from factory. 7″ to 11″ Clamps: Large bridge pin with 1/2″ wide Nitrile seal from factory. 12″ to 24″ Clamps: Large bridge pin with 5/8″ wide Nitrile seal from factory.
