This fitting connects the main plenum to branch supply runs, allowing conditioned air to be routed through small-diameter ducts typical of high-velocity systems. It incorporates a SmartSeal design intended to simplify and secure duct connections during installation. Weighing 7 pounds, the 45ac-sm9-t is a substantial, purpose-built fitting suited for installation by licensed HVAC technicians working with high-velocity air distribution systems in residential and light commercial applications.\u003c\/p\u003e\n\u003cp\u003eThis plenum tee is used in high-velocity forced-air systems where space constraints require small-diameter, flexible supply tubing branching off a central plenum. It is typically installed in attic spaces, crawl spaces, or mechanical rooms as part of a complete SpacePak-type distribution layout. The SmartSeal feature supports leak-resistant connections without the need for additional sealing tape or mastic in the connection zone, helping maintain system static pressure integrity throughout the distribution network.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eRound plenum tee configuration for high-velocity mini-duct air distribution systems\u003c\/li\u003e\n  \u003cli\u003eSmartSeal connection design for secure, leak-resistant branch connections\u003c\/li\u003e\n  \u003cli\u003eSubstantial 7-pound construction indicating durable, rigid fitting materials\u003c\/li\u003e\n  \u003cli\u003eDesigned to maintain static pressure integrity in high-velocity duct systems\u003c\/li\u003e\n  \u003cli\u003eSuited for residential and light commercial high-velocity HVAC installations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation fitting for high-velocity round plenum duct systems requiring a tee branch outlet configuration.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician familiar with high-velocity air distribution systems. Shut down and de-energize the air handling unit before working on the plenum or any duct connections. Follow the system manufacturer's guidelines for plenum tee placement and branch spacing to maintain balanced airflow. Verify all connections are fully seated and secured per the SmartSeal design requirements before restoring system operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProduct Type\u003c\/strong\u003e: Round Plenum Duct Tee\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 7 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShipping Weight\u003c\/strong\u003e: 6.90 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShipping Width\u003c\/strong\u003e: 20.20 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShipping Length\u003c\/strong\u003e: 20.30 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShipping Height\u003c\/strong\u003e: 10.60 inches\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: SPACEPAK\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 45ac-sm9-t\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPACEPAK","offers":[{"title":"Default Title","offer_id":51150016282930,"sku":"45AC-SM9-T","price":158.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/renderImage_1d4a1d27-1090-4ce9-8cf8-9fbf22ecd9fc.jpg?v=1778604157","url":"https:\/\/voomisupply.com\/products\/spacepak-45ac-sm9-t-round-plenum-duct-tee","provider":"Voomi Supply","version":"1.0","type":"link"}
