Continental Contitech 20042484 Cogged V-belt 3VX 25 in

Product Description

The CONTINENTAL CONTITECH 20042484 is a cogged V-belt in the 3VX cross-section, designed for high-efficiency power transmission in belt-driven equipment. Built from fiber-reinforced Wingprene rubber, this belt delivers oil resistance and flexibility across a wide range of operating conditions. The 3VX profile features a notched underside that reduces bending resistance, allowing the belt to run cooler and transfer power more efficiently than standard V-belts. With a 25-inch outside length and the HY-T Wedge Matchmaker Cogged construction, it is well suited for applications where precise belt matching and reduced slip are required. Licensed HVAC technicians and mechanical contractors are the primary installers.

This belt is a direct fit for belt-driven blower and fan assemblies commonly found in residential and light commercial HVAC systems, as well as general industrial drive applications. The 3VX250 designation is the standard belt number used to cross-reference fitment in motor-to-blower wheel drive configurations. It is also used in pumps, compressors, and other rotating equipment that calls for a narrow cogged V-belt in the 3VX section. When replacing a worn or cracked belt, confirm the belt section and outside length on the drive nameplate or equipment manual before ordering.

Key Features

• 3VX cogged profile reduces bending resistance and heat buildup compared to standard V-belts
• Fiber-reinforced Wingprene rubber construction for durability and oil resistance
• HY-T Wedge Matchmaker Cogged design for precise belt-to-belt matching in multi-belt drives
• 25-inch outside length suits a wide range of blower and fan drive configurations
• Oil-resistant compound extends service life in environments with lubricant exposure

Compatibility

Designed as an OEM-style replacement for equipment requiring a 3VX section cogged V-belt with a 25-inch outside length. The standard belt number for this specification is 3VX250.

Installation Notes

Belt replacement is typically performed by licensed HVAC technicians or qualified mechanical contractors. Always de-energize the equipment and lock out the power supply before removing drive guards or handling belts. Inspect sheaves and pulleys for wear, misalignment, or damage before installing the new belt. Do not pry the belt over a sheave flange; loosen the motor mount to relieve tension before seating the belt, then re-tension per the equipment manufacturer's specifications.
