Continental Contitech 20042487 Cogged V-belt 3VX 30 in

Product Description

The CONTINENTAL CONTITECH 20042487 is a 3VX-section cogged V-belt built for demanding drive applications in HVAC, industrial, and commercial equipment. Manufactured from fiber-reinforced Wingprene rubber, this belt delivers strong power transmission combined with oil resistance. The cogged profile reduces bending resistance and heat buildup, allowing operation on smaller-diameter sheaves without sacrificing belt life. It carries the belt designation 3VX300, corresponding to a 30-inch outside length. HVAC technicians and mechanical contractors use this belt as a direct replacement or upgrade in fan and blower drive systems where standard V-belts fall short under elevated loads or contaminated conditions.

This belt is suited for residential and light commercial HVAC blower drives, agricultural equipment, compressors, and general industrial power-transmission applications that call for a 3VX cogged section. The HY-T Wedge Matchmaker cogged design makes it compatible with standard 3VX-groove sheaves. It is sold individually and is appropriate wherever the 3VX300 belt designation is specified by the equipment manufacturer or engineering drawings.

Key Features

• 3VX cogged section reduces flex fatigue and runs cooler on small-diameter sheaves
• Fiber-reinforced Wingprene rubber construction for durability and oil resistance
• Oil-resistant compound suitable for environments with lubricant exposure
• HY-T Wedge Matchmaker cogged style for use with standard 3VX sheave profiles
• 30-inch outside length (belt number 3VX300) for direct OEM-style replacement

Compatibility

Designed for use with standard 3VX-groove sheaves in fan, blower, compressor, and general industrial drive systems requiring a cogged V-belt with a 30-inch outside length and 3VX section designation.

Installation Notes

Installation should be performed by a qualified HVAC technician or mechanical contractor. Disconnect and lock out all power to the drive system before removing or installing the belt. Never force the belt over sheave flanges using a pry bar, as this can damage the belt cords. After installation, verify proper belt tension and sheave alignment according to the equipment manufacturer specifications before returning the unit to service.
