Non-Metallic Expansion/Deflection Coupling

The new T&B® Fittings Non-Metallic Expansion/Deflection Coupling from Thomas & Betts (T&B) improves safety and reduces installation time for joining rigid polyvinylchloride (PVC) conduit that is subject to movement in any direction at structural joints. Its design makes the T&B® Fittings Non-Metallic Expansion/Deflection Coupling up to five times faster to install, while its versatility enables a five-to-one reduction in stock keeping units (SKUs). The T&B® Fittings Non-Metallic Expansion/Deflection Coupling is manufactured in the United States.

“The new, patent-pending T&B® Fittings Non-Metallic Expansion/Deflection Coupling provides a flexible connection of PVC conduit runs that resists moisture ingress and stress caused by movement at structural joints,” said Chad Smith, vice president, product management and marketing, at Thomas & Betts. “It safely accommodates axial or parallel deflection of up to 3/4 inch, and angular deflection up to 30 degrees from the relaxed position. It can be used indoors or outdoors, for direct burial or embedded in concrete.” The T&B® Fittings Non-Metallic Expansion/Deflection Coupling complies with 2014 National Electric Code® (NEC®) Article 300.4(H) for use where a raceway crosses a structural joint intended for expansion, contraction or deflection in buildings, bridges, parking garages, piers, hospitals, and water and waste water treatment plants. Additional features include a flexible neoprene outer jacket with tamperproof stainless steel straps for resistance to moisture and corrosion, and an inner sleeve to provide a constant and smooth inner diameter in any position to facilitate wire pulling and prevent damage to wire insulation.
