Continental Contitech 20042131 V-belt Section B B120 123 in

Product Description

The CONTINENTAL CONTITECH 20042131 is a Section B V-belt designed for industrial and HVAC drive applications requiring a durable, matched-drive-compatible belt. Built from Wingprene rubber-impregnated fabric, this belt delivers reliable torque transfer across a wide temperature range, rated from -40 degrees F to 284 degrees F (140 degrees C). The belt carries a B120 designation, with an outside length of 123 inches and an internal length of 121.80 inches. Licensed HVAC technicians, millwrights, and mechanical contractors install this belt on blower drives, fan assemblies, and equipment requiring a standard B-section profile.

This V-belt suits residential and commercial HVAC blower drives, industrial fan drives, pump drives, and general power-transmission applications where a Section B profile is specified. The HY-T Matchmaker style designation means this belt is engineered for use in matched sets on multi-groove sheave drives, maintaining consistent tension across all belt positions. It is appropriate for equipment specified with a B120 belt designation.

Installation Notes

Installation is typically performed by licensed HVAC technicians or qualified mechanical contractors. Always de-energize and lock out the drive system before removing or installing belts. Do not use tools to force the belt over sheave flanges — release drive tension before seating the belt, then re-tension per equipment manufacturer specifications. Inspect sheave grooves for wear before installing a new belt.
