Product Description

The VALUE COLLECTION 20526969 is a Section B classic V-belt designed for general power transmission in HVAC, industrial, and mechanical equipment applications. Built from rubber, this belt measures 74.9 inches outside length with an internal length of 73.80 inches and carries the standard belt designation B72. Section B belts are the workhorse of the industry, fitting a wide range of blower, compressor, and fan drive systems where reliable torque transfer is required. At 0.88 pounds, this belt is easy to handle during single-tech service calls.

This V-belt is suited for use in residential and light commercial HVAC systems, agricultural equipment, industrial machinery, and pump drives that specify a Section B belt. The B72 designation is a recognized standard size, making it a direct replacement for worn or failed belts in systems with matching sheave groove profiles. HVAC technicians frequently use this belt on belt-drive air handlers, supply fans, and condenser fans during routine maintenance or emergency service.

Installation Notes

Section B V-belts are installed by licensed HVAC technicians and mechanical service professionals. Always disconnect and lock out electrical power to the equipment before removing or installing a drive belt. Use a belt tension gauge when available to achieve proper deflection and avoid premature wear from over- or under-tensioning. Never use belt dressing compounds on rubber V-belts, as this can degrade the belt material and cause slippage.
