Thomas & Betts Corporation (www.tnb.com), a world leader in the manufacture, design and marketing of electrical components for construction, industrial and utility markets, has introduced the T&B Fitting XD Expansion/Deflection Coupling, which supports thermal expansion and movement in conduit runs to deliver a watertight and flexible connection.
The new coupling features a protective stainless-steel inner sleeve that makes wire installation easier, while its Erickson conduit union reduces installation effort and time. Supporting up to three-quarter inch of axial or parallel movement, the T&B Fitting XD Expansion/Deflection Coupling also accommodates up to 30 degrees of angular movement from normal position.
“The stainless-steel inner sleeve used in the T&B® Fitting XD Expansion/Deflection Coupling is far more durable than the conventional plastic tubes or corrugated hose found in other couplings of this kind,” said Bogdan Diaconescu, Product Manager for Thomas & Betts.
“It also provides better protection and easier wire pulling,” he added.
Specifically designed for rigid conduit, the T&B Fitting XD Expansion/Deflection Coupling features copper ground mounting plates that have been enclosed and secured with tamperproof jacket straps. It is made of stainless steel to impede vandalism and theft. The coupling also comes with ductile cast iron dual-layer hubs that have been coated with aluminum acrylic paint and zinc plated to protect it against corrosion.
CSA Certified to C22.2 No. 18.3, the new coupling is also UL Listed to UL 514B, making it ideal for wet locations. It is also NEC Article 250.98 compliant and is watertight pursuant to NEMA 4.
