Suitable for use in demanding outdoor environments, this weatherproof coupling is ideal for structures prone to movement such as bridges, railroads, and buildings. Its internal grounding design eliminates the need for external bonding jumpers and cables, making it a reliable component for electrical distributors and switchgear suppliers requiring durable conduit connections.\u003c\/p\u003e\n\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eManufacturer Part #: TXJG104HDG\u003c\/li\u003e\n  \u003cli\u003eProduct Weight: 21.6 lbs\u003c\/li\u003e\n  \u003cli\u003eSize: 4 inches\u003c\/li\u003e\n  \u003cli\u003eMaterial: Steel body, malleable iron reducer, washer, and bushing\u003c\/li\u003e\n  \u003cli\u003eFinish: Hot dip galvanized\u003c\/li\u003e\n  \u003cli\u003eGrounding Spring: Beryllium bronze-electrogalvanized\u003c\/li\u003e\n  \u003cli\u003ePacking and Gasket: PTFE composite\u003c\/li\u003e\n  \u003cli\u003eUL Listing: c(UL)us listed for wet locations\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eAllows up to 4\" of linear movement (2\" in either direction from center)\u003c\/li\u003e\n  \u003cli\u003eInternal grounding design eliminates need for external bonding jumpers and cables\u003c\/li\u003e\n  \u003cli\u003ePrevents conduit buckling and circuit failures\u003c\/li\u003e\n  \u003cli\u003eWeatherproof design suitable for outdoor structures subject to movement\u003c\/li\u003e\n  \u003cli\u003eHot dip galvanized finish provides superior protection against severe environmental factors\u003c\/li\u003e\n  \u003cli\u003eCompatible with Rigid UL 6 Conduit\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDownloads \u0026amp; Links\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\u003ca href=\"https:\/\/media.distributordatasolutions.com\/topaz\/2021q3\/documents\/50c1bcdc713cf8e2614dfb82a3bb92bb0474264d.pdf?did=4169\u0026amp;pid=9114035\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eSpec Sheet\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"https:\/\/media.distributordatasolutions.com\/topaz\/2021q3\/documents\/67e2b79ce90b43a50bb9fbf78513716b3ba0bc57.pdf?did=4169\u0026amp;pid=9114035\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eInstallation Instructions-Expansion Couplings\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Southwire","offers":[{"title":"Default Title","offer_id":48743906902271,"sku":"193070","price":841.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0805\/5868\/6463\/files\/1a884c0b1dfb9822745ca6b900985db2aa10f535-large.png?v=1782467231","url":"https:\/\/hunkshome.com\/products\/4-expansion-coupling","provider":"HunksHome®","version":"1.0","type":"link"}
