Commonly installed in industrial facilities, commercial buildings, utility infrastructure, and electrical distribution systems, this three-piece coupling features a malleable iron body with a steel center ring to provide a secure, concrete-tight connection and dependable grounding. Electricians, maintenance technicians, and contractors use this coupling for new installations, retrofits, repairs, and replacement of threaded conduit connections. \u003cspan data-state=\"closed\" class=\"\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3 data-end=\"755\" data-start=\"738\" data-section-id=\"5ms9th\"\u003eApplications:\u003c\/h3\u003e\n\u003cp data-end=\"1168\" data-start=\"757\"\u003eThe Thomas \u0026amp; Betts TB677 is designed for joining threaded ends of rigid metal conduit and IMC without rotating either conduit section. It is ideal for electrical raceways in manufacturing plants, commercial buildings, substations, utility installations, and other industrial environments where a strong mechanical connection and reliable electrical continuity are required. \u003cspan data-state=\"closed\" class=\"\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3 data-end=\"1199\" data-start=\"1170\" data-section-id=\"5hg6bl\"\u003eTechnical Specifications:\u003c\/h3\u003e\n\u003cp data-end=\"2383\" data-start=\"1201\"\u003e• Manufacturer Part Number (MPN): TB677 \/ 677\u003cbr data-end=\"1249\" data-start=\"1246\"\u003e• Brand: Thomas \u0026amp; Betts (ABB) – Erickson®\u003cbr data-end=\"1293\" data-start=\"1290\"\u003e• Product Type: Threaded Erickson Conduit Coupling (3-Piece)\u003cbr data-end=\"1356\" data-start=\"1353\"\u003e• Trade Size: 1 in.\u003cbr data-end=\"1378\" data-start=\"1375\"\u003e• Conduit Compatibility: Rigid Metal Conduit (RMC) and Intermediate Metal Conduit (IMC)\u003cbr data-end=\"1468\" data-start=\"1465\"\u003e• Connection Type: Threaded\u003cbr data-end=\"1498\" data-start=\"1495\"\u003e• Construction: Three-Piece Coupling with Steel and Malleable Iron Center Ring\u003cbr data-end=\"1579\" data-start=\"1576\"\u003e• Material: Malleable Iron Body with Steel\/Malleable Iron Ring\u003cbr data-end=\"1644\" data-start=\"1641\"\u003e• Finish: Zinc Electroplated Chromate-Coated\u003cbr data-end=\"1691\" data-start=\"1688\"\u003e• Outside Diameter: 1-29\/32 in.\u003cbr data-end=\"1725\" data-start=\"1722\"\u003e• Length: 1-5\/8 in.\u003cbr data-end=\"1747\" data-start=\"1744\"\u003e• Installation: Allows coupling where neither conduit length can be rotated\u003cbr data-end=\"1825\" data-start=\"1822\"\u003e• Grounding: Provides high-quality electrical bonding and grounding continuity\u003cbr data-end=\"1906\" data-start=\"1903\"\u003e• Construction Rating: Concrete-Tight\u003cbr data-end=\"1946\" data-start=\"1943\"\u003e• Standards: UL Listed (UL E23018), CSA Certified\u003cbr data-end=\"1998\" data-start=\"1995\"\u003e• Features: Free-fitting threads, vibration-resistant connection, high mechanical strength, suitable for carrying ground fault currents in accordance with product ratings\u003cbr data-end=\"2171\" data-start=\"2168\"\u003e• Typical Applications: Industrial Plants, Commercial Buildings, Utility Installations, Manufacturing Facilities, Electrical Distribution Systems, Rigid Conduit Installations \u003cspan data-state=\"closed\" class=\"\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3 data-end=\"2409\" data-start=\"2385\" data-section-id=\"1cz0398\"\u003eCommon Replacements:\u003c\/h3\u003e\n\u003cp data-is-only-node=\"\" data-is-last-node=\"\" data-end=\"2521\" data-start=\"2411\"\u003e• Thomas \u0026amp; Betts TB676\u003cbr data-end=\"2436\" data-start=\"2433\"\u003e• Thomas \u0026amp; Betts TB678\u003cbr data-end=\"2461\" data-start=\"2458\"\u003e• Thomas \u0026amp; Betts TB679\u003c\/p\u003e","brand":"THOMAS","offers":[{"title":"New","offer_id":51714008547630,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_2206155b-b11e-452b-8253-1072b8ffc404.jpg?v=1770413628","url":"https:\/\/plgautomation.com\/products\/thomas-betts-tb677-threaded-conduit-coupling","provider":"PLG Automation ","version":"1.0","type":"link"}
