Continental Contitech 20042092 V-belt Section B 77 in B74

Product Description

The CONTINENTAL CONTITECH 20042092 is a Section B classical V-belt designed for industrial and HVAC drive applications. Constructed from Wingprene rubber-impregnated fabric, this belt delivers reliable power transmission across a wide operating temperature range, from -40 degrees F to 284 degrees F. It carries the belt designation B74, with a 77.0-inch outside length and a 75.80-inch internal length. The HY-T Matchmaker profile is engineered for consistent performance in matched-belt and single-belt drive configurations. HVAC technicians, mechanical contractors, and industrial maintenance professionals install this belt on fan, blower, and motor drive systems.

This belt fits standard Section B sheave and pulley drives found in residential and light commercial HVAC systems, including air handling units, rooftop units, and exhaust fan assemblies. It is also used on agricultural, industrial, and general-purpose drive systems requiring a Section B cross-section. The Wingprene rubber-impregnated fabric construction resists heat, oil, and environmental exposure, making it suitable for both indoor mechanical rooms and outdoor equipment installations.
