Fabricated from hot-dip galvanized steel at 24 gauge, it provides corrosion resistance and structural integrity suited to both supply and return air applications. The cap seats over the open end of spiral pipe to prevent airflow bypass, contain static pressure, and keep debris out of unused duct sections. Licensed HVAC technicians and sheet metal contractors are the primary installers in commercial and light commercial construction and retrofit projects.\u003c\/p\u003e\n\u003cp\u003eThis end cap is used in low- to medium-pressure HVAC ductwork systems where 14-inch spiral pipe is installed. Typical applications include capping unused branch takeoffs, sealing temporary openings during phased construction, and permanently terminating dead-end duct runs. The 24-gauge galvanized construction meets the material and thickness standards commonly specified on commercial mechanical drawings for round spiral duct accessories.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e14-inch diameter fits standard 14-inch spiral duct and pipe\u003c\/li\u003e\n  \u003cli\u003e24-gauge hot-dip galvanized steel construction for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eMeets ACCA and SMACNA applicable standards for sheet metal duct accessories\u003c\/li\u003e\n  \u003cli\u003eSeals open pipe ends to prevent airflow bypass and pressure loss\u003c\/li\u003e\n  \u003cli\u003eSuitable for supply, return, and exhaust duct termination points\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style sheet metal accessory for use with 14-inch diameter spiral round duct and pipe systems fabricated to SMACNA and ACCA standards.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed sheet metal contractors or HVAC technicians following SMACNA round duct construction standards. Power down the air handling unit and verify zero static pressure in the duct section before fitting the cap. Secure the cap with sheet metal screws and apply UL-listed duct sealant at the joint per SMACNA sealing class requirements. Do not use this cap as a fire-rated assembly unless independently listed for that purpose.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Hot Dip Galvanized Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Thickness\u003c\/strong\u003e: 24 Gauge\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 14 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplicable Standards\u003c\/strong\u003e: ACCA, SMACNA\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SOUTHWARK METAL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: SP55-24GA_14IN\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHWARK METAL","offers":[{"title":"Default Title","offer_id":51283973374258,"sku":"SP55-24GA_14IN","price":43.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309277996.jpg?v=1781064675","url":"https:\/\/voomisupply.com\/products\/southwark-metal-sp55-24ga_14in-spiral-pipe-end-cap-14-in","provider":"Voomi Supply","version":"1.0","type":"link"}
