Moulded from high-strength Polyamide 6 (PA6), this dome-style connector handles cable diameters from 0.51\" to 0.71\" and delivers IP68 (5 Bar) and IP69K dual ratings — making it equally at home in wet industrial environments, outdoor enclosures, and washdown applications. The included O-ring and locknut ensure a watertight, vibration-resistant seal right out of the box, saving installation time on the job site. UL-listed (E360400), the RDC21NA is a practical, code-compliant choice for panel builders, industrial electricians, and OEM assemblers who need consistent performance at volume.\u003c\/p\u003e\n\u003ch3 style=\"font-size: 1.1em; font-weight: bold; margin-top: 20px; margin-bottom: 10px;\"\u003eSpecifications\u003c\/h3\u003e\n\u003ctable style=\"width: 100%; border-collapse: collapse; margin-bottom: 20px;\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #ddd; font-weight: bold; width: 40%;\"\u003eItem Type\u003c\/td\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #ddd;\"\u003eNPT Nylon Cord Grip\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #ddd; font-weight: bold; width: 40%;\"\u003eThread Size\u003c\/td\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #ddd;\"\u003e3\/4\" NPT\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #ddd; font-weight: bold; width: 40%;\"\u003eCable Range\u003c\/td\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #ddd;\"\u003e0.51\" – 0.71\" (13.0 – 18.0 mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #ddd; font-weight: bold; width: 40%;\"\u003eMaterial\u003c\/td\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #ddd;\"\u003ePolyamide 6 (PA6 Nylon)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #ddd; font-weight: bold; width: 40%;\"\u003eColour\u003c\/td\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #ddd;\"\u003eBlack\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #ddd; font-weight: bold; width: 40%;\"\u003eGrip Length (GL)\u003c\/td\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #ddd;\"\u003e0.551\" (14 mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #ddd; font-weight: bold; width: 40%;\"\u003eOverall Height (H)\u003c\/td\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #ddd;\"\u003e1.220\" (31 mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #ddd; font-weight: bold; width: 40%;\"\u003eProtection Class\u003c\/td\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #ddd;\"\u003eIP68 (5 Bar), IP69K\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #ddd; font-weight: bold; width: 40%;\"\u003eIncludes\u003c\/td\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #ddd;\"\u003eO-ring and locknut\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #ddd; font-weight: bold; width: 40%;\"\u003eUL Listing\u003c\/td\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #ddd;\"\u003eE360400\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #ddd; font-weight: bold; width: 40%;\"\u003eManufacturer\u003c\/td\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #ddd;\"\u003eTechspan\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"TECHSPAN","offers":[{"title":"Default Title","offer_id":48242347409663,"sku":"TSP-RDC21NA","price":2.73,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0741\/0479\/9487\/files\/4071830156_RDC21NA.jpg?v=1786378490","url":"https:\/\/shop.iesupply.ca\/products\/techspan-dome-connector-750in-npt-51-71in-grey-c-w-o-ring-and-locknut-model-rdc21na","provider":"Independent Electric Supply","version":"1.0","type":"link"}
