Continental Contitech 20042495 Cogged V-belt 3VX 45 in

Product Description

The CONTINENTAL CONTITECH 20042495 is a 3VX-section cogged V-belt designed for power transmission in HVAC, industrial, and mechanical drive applications. Built from fiber-reinforced Wingprene rubber, this belt delivers reliable grip and flexibility across a range of operating conditions. The cogged profile reduces bending resistance, allowing it to run cooler and operate efficiently on smaller-diameter sheaves. With a 45-inch outside length and the HY-T Wedge Matchmaker Cogged design, it is a direct-fit replacement for standard 3VX450 belt applications. Licensed HVAC technicians and mechanical service professionals are the primary installers.

This belt fits residential and light commercial HVAC systems, blower drives, and general-purpose mechanical equipment requiring a 3VX-section cogged belt. The 3VX450 designation confirms compatibility with drive systems engineered for that specific section and outside length. It is also used in agricultural, pump, and fan drive configurations where oil resistance and cogged construction are specified. Always verify sheave groove profile and center-to-center distance before installation to confirm proper fit.

Key Features

• 3VX cogged section reduces bending resistance for cooler, more efficient operation
• Fiber-reinforced Wingprene rubber construction for durability and flex life
• Oil-resistant formulation suitable for environments with incidental oil exposure
• HY-T Wedge Matchmaker Cogged design for matched-set drive compatibility
• 45-inch outside length corresponding to the 3VX450 belt number

Compatibility

Designed as a direct replacement for 3VX450 cogged V-belt applications in HVAC blower drives, fan drives, and general mechanical power transmission systems requiring a 3VX-section belt with a 45-inch outside length.

Installation Notes

Installation is typically performed by HVAC technicians or mechanical service professionals. De-energize the equipment and lock out the power source before removing the old belt or accessing the drive sheaves. Never pry or force the belt over sheave flanges — adjust center-to-center distance to allow proper belt seating. After installation, verify belt tension and sheave alignment per the equipment manufacturer's specifications before returning the unit to service.
