Expanding Duct Seals

The 58400 series duct seals are constructed of a specially formulated polyurethane that has maximum sealing and expansion properties.The seals are color coded for easy recognition of size and correspond with the colors on 58300 Line Darts which cover 2" to 8" nominal duct sizes.

Single seals are very difficult to properly align, and double seals are very expensive. These seals however feature an an alignment washer with a single seal, making them both ecomomical and effective.

The Handle Assembly features a quick release coupling and is designed to support all sizes of the interchangeable Seal Kits. Adjusting for new duct sizes is easy, simply unscrew the two nuts, swap out the Seal Kit, and replace the nuts.

All seals have been tested to at least 15% higher than stated values. The actual pressure attained may depend on the condition of both the duct and the Seal Kit. Care should be taken at all times when working with pressurized systems.
