They vibrate. The vibration is small, but it&#8217;s continuous, and it has frequencies that resonate well in metal ducting. Without a flexible connector between the equipment and the duct, those vibrations transmit straight into the rigid ductwork and travel throughout the building. The result is humming, rattling, and low frequency rumble that occupants notice immediately.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The flexible canvas duct connector solves this by inserting a fabric break between the vibrating equipment and the rigid duct. The fabric absorbs the vibration energy instead of transmitting it. The metal sleeves on each side connect to the equipment and ductwork using standard sheet metal practice. Three inches of fabric in the middle is enough to break the vibration path while still maintaining an airtight seal.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The 2x3x2 size (two inches of metal sleeve, three inches of fabric, two inches of metal sleeve) is the most common configuration for slip and drive duct fabrication, which is the standard ducting method for residential, light commercial, and most retail HVAC installations across Saudi Arabia.<\/span><\/p>\n<h2><strong>How the 2x3x2 Flexible Connector Size Improves HVAC Performance<\/strong><\/h2>\n<p><span style=\"font-weight: 400;\">The numbers describe the cross section profile. Two inches of metal sleeve on the equipment side, three inches of flexible fabric in the middle, and two inches of metal sleeve on the duct side. When the fabricator forms this profile into a four sided rectangular sleeve and installs it between the equipment and the duct, the result is a flexible joint that handles vibration isolation while keeping the air seal intact.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">For TDC\/TDF style duct fabrication (which uses a different edge profile), the 4x4x4 configuration is more common because the wider metal sleeves accommodate the TDC\/TDF flange. For standard slip and drive duct, the 2x3x2 (sometimes also seen as 3x3x3 depending on installer preference) is the standard.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The fabric width of three inches is also a code requirement. NFPA 90A and 90B specify that <\/span><a href=\"https:\/\/cool.sa\/ar\/product\/rubber-pads-anti-vibration\/\"><span style=\"font-weight: 400;\">vibration isolation <\/span><\/a><span style=\"font-weight: 400;\">connectors made of fabric shall not exceed 10 inches in length. The standard 3 inch fabric width sits comfortably within that limit.<\/span><\/p>\n<h2><strong>How to Fabricate and Install Flexible Duct Connectors<\/strong><\/h2>\n<p><span style=\"font-weight: 400;\">The 100 foot roll arrives at the site or fabrication shop ready to use. The fabricator pulls the appropriate length off the roll, forms it into a four sided rectangular sleeve sized to the duct opening, and finishes the metal edges to match the duct profile (slip and drive in this case).<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Some fabrication shops add a 90 degree bend to the metal edges to stiffen the sleeve and make alignment easier during installation. The finished sleeve goes between the fan or AHU outlet and the rigid duct, secured to both sides with standard sheet metal connections.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Installation tip: never stretch the fabric tight during installation. The fabric needs to hang slightly slack so it can absorb vibration without transmitting it. A taut fabric defeats the purpose of the connector.<\/span><\/p>\n<h3><strong>Where and When to Use Flexible Duct Connectors in HVAC Systems<\/strong><\/h3>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">AHU and FCU connection to supply and return ductwork<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Fan and blower discharge connections<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Packaged HVAC unit ductwork connections<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Rooftop unit duct connections<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Industrial fan and exhaust duct connections<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Kitchen exhaust hood ducting (with appropriate temperature rated fabric)<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Manufacturing and process ventilation<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Office, retail, and institutional HVAC installations<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Hospital and healthcare HVAC where noise control is critical<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Hotel and hospitality HVAC systems<\/span><\/li>\n<\/ul>\n<h4><b>\u0627\u0644\u0645\u0648\u0627\u0635\u0641\u0627\u062a \u0627\u0644\u0641\u0646\u064a\u0629<\/b><\/h4>\n<table>\n<tbody>\n<tr>\n<td><span style=\"font-weight: 400;\">\u062a\u062e\u0635\u064a\u0635<\/span><\/td>\n<td><span style=\"font-weight: 400;\">\u062a\u0641\u0627\u0635\u064a\u0644<\/span><\/td>\n<\/tr>\n<tr>\n<td><span style=\"font-weight: 400;\">\u062a\u0643\u0648\u064a\u0646<\/span><\/td>\n<td><span style=\"font-weight: 400;\">2x3x2 (2 inch metal + 3 inch fabric + 2 inch<\/span><\/p>\n<p><span style=\"font-weight: 400;\">\u00a0\u00a0metal)<\/span><\/td>\n<\/tr>\n<tr>\n<td><span style=\"font-weight: 400;\">Metal Sleeve Material<\/span><\/td>\n<td><span style=\"font-weight: 400;\">Galvanised sheet steel (typical)<\/span><\/td>\n<\/tr>\n<tr>\n<td><span style=\"font-weight: 400;\">Fabric Type<\/span><\/td>\n<td><span style=\"font-weight: 400;\">Flame retardant coated fabric<\/span><\/td>\n<\/tr>\n<tr>\n<td><span style=\"font-weight: 400;\">Fire Rating<\/span><\/td>\n<td><span style=\"font-weight: 400;\">Meets NFPA 90A and 90B requirements<\/span><\/td>\n<\/tr>\n<tr>\n<td><span style=\"font-weight: 400;\">Flame Spread<\/span><\/td>\n<td><span style=\"font-weight: 400;\">Not over 25<\/span><\/td>\n<\/tr>\n<tr>\n<td><span style=\"font-weight: 400;\">Smoke Development<\/span><\/td>\n<td><span style=\"font-weight: 400;\">Not over 50<\/span><\/td>\n<\/tr>\n<tr>\n<td><span style=\"font-weight: 400;\">Roll Length<\/span><\/td>\n<td><span style=\"font-weight: 400;\">100 feet<\/span><\/td>\n<\/tr>\n<tr>\n<td><span style=\"font-weight: 400;\">Fabrication Method<\/span><\/td>\n<td><span style=\"font-weight: 400;\">Pre assembled, formed into sleeve on site<\/span><\/td>\n<\/tr>\n<tr>\n<td><span style=\"font-weight: 400;\">Suitable For<\/span><\/td>\n<td><span style=\"font-weight: 400;\">Slip and drive duct construction<\/span><\/td>\n<\/tr>\n<tr>\n<td><span style=\"font-weight: 400;\">Available Variants<\/span><\/td>\n<td><span style=\"font-weight: 400;\">Galvanised steel, aluminium, stainless steel (on<\/span><\/p>\n<p><span style=\"font-weight: 400;\">\u00a0\u00a0request)<\/span><\/p>\n<p><span style=\"font-weight: 400;\">\u00a0<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h2><strong>Why Cool.sa is the Best Source for Flexible Duct Connectors in Saudi Arabia<\/strong><\/h2>\n<p><span style=\"font-weight: 400;\">We supply canvas flexible duct connector to HVAC contractors, ducting fabricators, FM teams, and project ducting installers across Saudi Arabia.

What does 2x3x2 actually mean?<\/h4>\n<p>Two inches of metal sleeve, three inches of flexible fabric, two inches of metal sleeve. The fabric in the middle does the vibration isolation. The metal sleeves connect to the equipment on one side and the rigid ducting on the other.<\/p>\n<h4>Q2. Why not just connect the duct directly to the AHU?<\/h4>\n<p>Without a flexible connector, every vibration from the fan or blower transmits straight into the rigid ductwork and travels throughout the building. Occupants hear humming, rattling, and rumble. The flexible connector breaks the vibration path while keeping the air seal intact.<\/p>\n<h4>Q3. Can I use 2x3x2 for TDC\/TDF duct fabrication?<\/h4>\n<p>For TDC\/TDF duct, the 4x4x4 size is more common because the wider metal sleeves accommodate the TDC\/TDF flange profile. Using 2x3x2 with TDC\/TDF leaves the metal sleeve too narrow after the flange is formed. We stock both sizes.<\/p>\n<h4>Q4. Is the fabric fireproof?<\/h4>\n<p>The fabric is flame retardant treated to meet NFPA 90A and 90B requirements with flame spread under 25 and smoke development under 50. It&#8217;s not fireproof in absolute terms, but it meets the standards required for installation inside HVAC ductwork.<\/p>\n<h4>Q5. How long does the fabric last in service?<\/h4>\n<p>Indoor installations typically run for 10 to 20 years before fabric replacement is needed. Outdoor installations or harsh environments degrade faster due to UV and thermal cycling. Annual inspection is recommended.<\/p>","protected":false},"excerpt":{"rendered":"<p><span style=\"font-weight: 400;\">Buy 2x3x2 canvas flexible duct connector in Saudi Arabia from <strong><a href=\"https:\/\/cool.sa\/ar\/\">Cool.sa<\/a><\/strong>.
