Continental Contitech 20042079 V-belt Section B 64 in B61

Product Description

The CONTINENTAL CONTITECH 20042079 is a Section B classical V-belt designed for industrial and HVAC drive applications requiring reliable power transmission. Built from Wingprene rubber-impregnated fabric, this belt delivers strong resistance to heat, oil, and environmental exposure. It carries a 64-inch outside length (62.80-inch internal length) and is catalogued under belt number B61. The HY-T Matchmaker construction allows matched-set use on multi-groove drive systems. Licensed trades and mechanical contractors install this belt on belt-driven blowers, fans, compressors, and pump assemblies where a Section B profile is specified.

This V-belt fits residential and light commercial HVAC air handlers, furnace blower assemblies, and general industrial drive systems that call for a B-section belt. It is rated for operating temperatures from -40 degrees F to 284 degrees F (corresponding to -40 C to 140 C), making it suitable for both cold-storage and high-ambient environments. Packaged as a single unit, it is stocked and replaced one-for-one on standard B-section sheaves and pulleys wherever a B61-designation belt is required.

Installation Notes

Installation is typically performed by a licensed HVAC technician or mechanical contractor. Disconnect and lock out all power to the drive unit before removing the old belt or handling the sheave. Do not pry or force the belt over the sheave flanges; always release drive tension via the motor adjustment slot or idler before seating the new belt. After installation, verify belt tension and sheave alignment per the equipment manufacturer's specifications before restoring power.
