Continental Contitech 20042096 V-belt Section B 81in B78

Product Description

The CONTINENTAL CONTITECH 20042096 is a Section B classical V-belt rated for demanding power transmission applications in HVAC, industrial, and mechanical drive systems. Constructed from Wingprene rubber-impregnated fabric, this belt delivers reliable grip and flex fatigue resistance across a wide operating temperature range of -40 degrees F to 284 degrees F (approximately -40 degrees C to 140 degrees C). The belt carries a B78 designation with an outside length of 81.0 inches and an internal length of 79.80 inches. It is a HY-T Matchmaker style belt, engineered for matched-set compatibility and consistent power transmission across the full belt cross section.

This belt is suited for use on blower drives, fan systems, pump drives, and general industrial equipment that use standard Section B sheaves. It is commonly installed on belt-driven HVAC air handlers, rooftop units, condensing units with belt-drive fans, and light industrial machinery. The B-section profile fits standard B-groove pulleys. Technicians often replace this belt as part of routine preventive maintenance schedules or when a belt shows cracking, glazing, or slippage under load.

Installation Notes

Belt installation should be performed by a qualified HVAC technician or mechanical trades professional. Always shut off and lock out the equipment before removing belt guards or handling drive components. Never pry a belt over a sheave with tools that could damage the belt cords; move the motor adjustment to relieve tension before installation. After installing, verify proper belt tension and sheave alignment before restoring power to the unit.
