Carrying belt number 4L310, it features a 4L cross-section with a 31-inch outside length and a 30-inch internal length. The belt is constructed from high traction rubber, offering a flexible cogged profile that reduces bending resistance and heat buildup during operation. It is rated for working temperatures from -40 degrees C to 140 degrees C, making it suitable for both cold-storage and high-heat environments. Licensed HVAC technicians and mechanical service professionals are the primary installers.\u003c\/p\u003e\u003cp\u003eThis belt fits typical fractional horsepower drive systems found in residential and light commercial HVAC units, including belt-driven air handlers, furnace blower assemblies, condenser fan drives, and similar equipment. The 4L section is a standard fractional horsepower profile widely used in OEM blower and fan drive configurations. The cogged design improves grip on smaller-diameter sheaves and increases flexibility compared to a standard wrapped belt of the same section.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCogged profile reduces heat buildup and improves flexibility on small-diameter sheaves\u003c\/li\u003e\n\u003cli\u003eHigh traction rubber construction for reliable grip and power transfer\u003c\/li\u003e\n\u003cli\u003eAbrasion resistant and ozone resistant for extended service life\u003c\/li\u003e\n\u003cli\u003eWide operating temperature range: -40 degrees C to 140 degrees C\u003c\/li\u003e\n\u003cli\u003e4L310 belt number — 4L section, 31-inch outside length, 30-inch internal length\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement fractional horsepower V-belt for belt-driven blower and fan assemblies using a 4L section drive sheave.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by a licensed HVAC technician or mechanical service professional. Disconnect and lock out all power to the unit before removing the old belt or accessing the drive assembly. Verify sheave alignment and sheave condition before installing the replacement belt, and set tension according to the equipment manufacturer specifications. Do not use belt dressing compounds on cogged V-belts, as these can degrade rubber and reduce service life.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBelt Number\u003c\/strong\u003e: 4L310\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBelt Section\u003c\/strong\u003e: 4L\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBelt Style\u003c\/strong\u003e: Fractional Horsepower V-Belt\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBelt Type\u003c\/strong\u003e: Cogged\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Length\u003c\/strong\u003e: 31 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInternal Length\u003c\/strong\u003e: 30 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High Traction Rubber\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Working Temperature\u003c\/strong\u003e: 140 degrees C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Working Temperature\u003c\/strong\u003e: -40 degrees C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eResistance Features\u003c\/strong\u003e: Abrasion Resistant, Ozone Resistant\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.19 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: CONTINENTAL CONTITECH\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 20043791\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CONTINENTAL","offers":[{"title":"Default Title","offer_id":51557657051442,"sku":"20043791","price":19.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a5384e7b94356afae1d2356a009d21c7.jpg?v=1786392150","url":"https:\/\/voomisupply.com\/products\/continental-contitech-20043791-cogged-v-belt-4l-31-in","provider":"Voomi Supply","version":"1.0","type":"link"}
