T&B® Fittings Non-Metallic Expansion/Deflection Coupling Now Compatible with Fiberglass Raceway

MEMPHIS, Tenn., Oct. 15, 2015 – T&B® Fittings Non-Metallic Expansion/Deflection Couplings from Thomas & Betts (T&B), developed for polyvinylchloride (PVC) systems, now are compatible with fiberglass raceway, also known as reinforced thermosetting resin conduit (RTRC), when bonded with methacrylate adhesive.

“The use of a methacrylate adhesive has enabled the expansion of the couplings’ applications beyond PVC systems to include RTRC systems,” said Ralph Donati, product marketing director at T&B. “Contractors now have the option of using T&B’s non-metallic expansion/deflection couplings in applications that require the strength and light weight of fiberglass. Their use with RTRC has been successful in pullout and water-tightness testing.”

T&B® Fittings Non-Metallic Expansion/Deflection Couplings provide flexible connections of PVC and fiberglass conduit runs that resist moisture ingress and stress caused by movement at structural joints. They safely accommodate axial or parallel movement of up to ¾ inch, and angular deflection up to 30 degrees from the relaxed position. The couplings may be used indoors or outdoors, for direct burial or embedded in concrete, and 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. They are NEC® compliant and UL® approved.
