The no-crimp style allows for straightforward installation without the need for additional forming or crimping tools. This type of fitting is a standard component in forced-air HVAC duct systems, used wherever a duct run must be permanently or temporarily capped off. HVAC installers and sheet metal contractors work with these fittings during new construction, renovation, and system modification projects. The galvanized finish provides corrosion resistance suitable for both conditioned and unconditioned space applications.\u003c\/p\u003e\u003cp\u003eThis end cap is suited for residential and light commercial HVAC ductwork where a 6-inch round duct termination is required. Common applications include capping unused branch takeoffs, sealing duct ends during rough-in before grille installation, and closing off decommissioned duct runs. The no-crimp design fits directly over the duct end without requiring the mating duct to be crimped down first, which simplifies installation in tight spaces or when working with duct sections that have already been cut to length.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e30-gauge galvanized steel construction for corrosion resistance in HVAC environments\u003c\/li\u003e\n\u003cli\u003eNo-crimp design fits directly over standard 6-inch round duct ends\u003c\/li\u003e\n\u003cli\u003eSeals duct terminations cleanly without additional forming tools\u003c\/li\u003e\n\u003cli\u003eLightweight at 0.313 pounds, easy to handle and carry on the job\u003c\/li\u003e\n\u003cli\u003eSingle-piece unit packaged individually for precise job-site quantities\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard fitting for 6-inch round galvanized ductwork in residential and light commercial forced-air HVAC systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by HVAC technicians and sheet metal contractors working on forced-air duct systems. Power down the air handling unit and any associated controls before accessing the duct system. Secure the end cap with sheet metal screws and seal the joint with UL 181-rated duct tape or mastic sealant as required by local mechanical codes. Inspect the fit before finalizing to confirm the cap seats flush against the duct end.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Galvanized Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGauge\u003c\/strong\u003e: 30 Ga.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStyle\u003c\/strong\u003e: No Crimp\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.313 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: IMPERIAL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: GV1399\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IMPERIAL","offers":[{"title":"Default Title","offer_id":68079497707826,"sku":"GV1399","price":15.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fd99ac0e342f301b5905b209d7ab9f95_793671d4-0e02-4b4d-bc60-e9e4f083cbd5.jpg?v=1793122618","url":"https:\/\/voomisupply.com\/products\/imperial-gv1399-galvanized-duct-end-cap-6-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
