Built from fiber reinforced Wingprene rubber and styled as a HY-T Wedge Matchmaker Envelope belt, it delivers reliable torque transfer under demanding conditions. The 3V section profile provides a wedge-fit engagement in matched-sheave drives, reducing slippage and heat buildup. With an outside length of 125 inches, this belt suits larger drive assemblies where standard fractional belts fall short. Oil resistance extends service life in environments where belt contact with lubricants is a factor.\u003c\/p\u003e\u003cp\u003eThis belt is a fit for commercial and industrial power transmission drives, including blower and fan assemblies commonly found in HVAC air handling units, industrial ventilation equipment, and pump drives. The 3V section is widely used in light-to-medium duty matched drives where precise belt geometry is critical for even load sharing. HVAC technicians and millwrights typically encounter this section in belt-drive fan and blower configurations requiring a longer span between sheaves.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3V wedge section profile for precise sheave engagement and reduced slippage\u003c\/li\u003e\n\u003cli\u003e125-inch outside length suits large-span drive configurations\u003c\/li\u003e\n\u003cli\u003eFiber reinforced Wingprene rubber construction for durability under tension and flex\u003c\/li\u003e\n\u003cli\u003eOil resistant compound resists degradation in lubricant-exposed environments\u003c\/li\u003e\n\u003cli\u003eHY-T Wedge Matchmaker Envelope style designed for use in matched-set drives\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement for 3V-section belt drives with a 125-inch outside length, also identified by belt number 3V1250.

Disconnect and lock out all power to the drive system before replacing the belt. Never force the belt over sheave flanges using a pry tool, as this can damage the reinforcement cords. After installation, verify belt tension and alignment per the equipment manufacturer's specifications before returning the system to service.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBelt Section\u003c\/strong\u003e: 3V\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Length\u003c\/strong\u003e: 125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBelt Number\u003c\/strong\u003e: 3V1250\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStyle\u003c\/strong\u003e: HY-T Wedge Matchmaker Envelope\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Fiber Reinforced Wingprene Rubber\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eResistance Features\u003c\/strong\u003e: Oil Resistant\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.578 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: 20042521\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CONTINENTAL","offers":[{"title":"Default Title","offer_id":51563794071858,"sku":"20042521","price":70.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/696398a4d76e9d4ff2d48d3a0065121f.jpg?v=1786503706","url":"https:\/\/voomisupply.com\/products\/continental-contitech-20042521-v-belt-3v-125-in","provider":"Voomi Supply","version":"1.0","type":"link"}
