Continental Contitech 20042491 3VX Cogged V-belt 35.5 in

Product Description

The CONTINENTAL CONTITECH 20042491 is a cogged V-belt designed for demanding power transmission applications in HVAC, industrial, and mechanical drive systems. Built from fiber-reinforced Wingprene rubber, this belt carries the designation 3VX355, indicating a 3VX cross-section and 35.5 inches outside length. The cogged design reduces bending resistance and heat buildup, which extends belt life in high-cycle or variable-load applications. The oil-resistant compound makes it suitable for environments where petroleum-based fluids may be present. HVAC technicians and mechanical service professionals install this belt as a direct drive component on fan, blower, and pump systems.

This belt is suited for use in residential and light commercial HVAC systems, as well as general industrial drive applications requiring a 3VX-section belt. The HY-T Wedge Matchmaker Cogged style is engineered for matched-set compatibility on multi-groove sheave drives, making it appropriate for blower assemblies, compressor drives, and other motor-to-load power transfer setups where consistent belt length and cross-section are critical for balanced operation.

Key Features

• 3VX cogged section reduces flex fatigue and operating temperature for extended service life
• Fiber-reinforced Wingprene rubber construction provides durability under high-load, high-cycle conditions
• Oil-resistant compound suitable for environments with incidental petroleum-fluid exposure
• HY-T Wedge Matchmaker Cogged style designed for use in matched-set multi-belt drive systems
• 35.5 inch outside length corresponding to belt number 3VX355 for straightforward replacement identification

Compatibility

Designed as an OEM-style replacement for drive systems requiring a 3VX-section cogged V-belt with a 35.5 inch outside length. Verify sheave groove profile and center-to-center distance against drive specifications before installation.

Installation Notes

V-belt replacement should be performed by a qualified HVAC technician or mechanical service professional with the drive system fully de-energized and locked out per OSHA lockout/tagout procedures. Adjust sheave center distance to allow belt installation without forcing the belt over the sheave rim, then set tension according to the drive manufacturer specifications. On multi-belt drives, replace all belts in the set simultaneously to maintain even load distribution and prevent premature wear. Inspect sheave grooves for wear or damage before installing a new belt.
