All parts of DanFLEX are pre-engineered, made to standard sizes, and are interchangeable. As a result, replacement lead time is reduced. Furthermore, in the event that the mating equipment is modifi ed and requires a different bolt-hole pattern, the fl ange can easily be replaced without having to change out the entire fl exible connector.Withstands Extreme Torsional ForcesDanFLEX fl exible connector is designed to absorb extreme and sudden torsional forces without wrinkling and (eventually) cracking of the molded elastomer volute. As an intended fail-safe feature, if excessive twisting forces are applied to the fl ex connector, the fl anges will slip inside the tubular elastomer sleeve instead of tearing it.Facilitates Accurate InstallationDanFLEX has an adjustable overall length, facilitating a more accurate fi t and fi nish when installing in parent duct/pipe spools which have fi nite length measurements. This is easily achieved by extending the length of either of the FRP fl anged stubs located at each end of the fl exible connector. Longer Warranty PeriodDaniel Company’s DanFLEX fl exible connector comes with double the warranty period offered by other manufacturers.Made of High Quality ConstructionDanFLEX is constructed of vulcanized layers of polyester tire-cord fabric reinforcement, sanwiched between a 60 to 70 durometer elastomeric inner liner and exterior cover. Tire-cord fabric is layered at an optimal bias angle with Resorcinol Formaldehyde Latex for superior rubber-to-fabric bonding. The elastomer is built as one continuous piece with an integrally molded, hollow-arched volute. 316 stainless steel retainer bands are used with adjustable screw seal type fasteners. DanFLEX is suitable for use in H2S-laden, corrosive environments, and is resistant to ultra violet rays.Features Superior FlexibilityDanFLEX fl exible connectors provide superior absorption of lateral, torsional, angular, and axial movement experienced in rigid ducting/piping systems due to thermal expansion and contraction, installation misalignment, and vibration.Eliminates High Stress PointsThe weakest point of a traditional fl exible connector design is located annularly – where the back of the integrally molded elastomer fl ange meets the tubular section. DanFLEX relieves this high stress area by overlapping the tubular elastomer onto the hubs of the FRP fl anges. Infi nite Bolt Hole Alignment CapabilityDanFLEX fl exible connector is designed to allow for infi nite adjustment capability to accommodate any degree of axial misalignment of bolt holes.
