Description
Product Summary
The Supco B52 Multi-Plus Dual Brand V-Belt is a professional-grade replacement part from Supco (Sealed Unit Parts Co.), a trusted name in HVAC/R and appliance parts since 1945. Clearly identifying RMA classic part number and dimensionally equivalent FHP number, the Multi-plus belt is designed to reduce total V-belt investment.
Fractional and industrial V-belts for air handlers, rooftop units, blowers, and exhaust fans. A worn or glazed belt slips, squeals, and cuts airflow, which raises energy use and can freeze coils. Match the belt section (3L, A/4L, B/5L, AX, BX) and the outside length of the original, and set proper tension after installation.

- 21/32" top width
