Jason Industrial A79 Rubber V-belt 1/2 X 81 Inch

Product Description

The JASON INDUSTRIAL A79 is a rubber V-belt designed for industrial power transmission applications. Built to standard A-section dimensions of 1/2 inch wide by 81 inches in length, this belt transfers rotational power between sheaves and pulleys in a wide range of mechanical drive systems. The A-section profile is one of the most common fractional-horsepower belt standards, making this a go-to replacement for general industrial, agricultural, and HVAC equipment. HVAC technicians, millwrights, and maintenance mechanics install this belt on belt-driven blowers, fans, compressors, and pumps where a reliable, OEM-compatible drive belt is required.

The A79 is suited for residential and light commercial applications involving belt-driven equipment. Common install scenarios include air handling units, belt-drive fan coils, agricultural machinery, and general industrial drive systems that use A-section sheaves. Its black rubber construction provides flexibility and durability across typical indoor and outdoor mechanical environments. This belt ships in a package quantity of 25 units, making it practical for service fleets and stocking distributors who maintain belt inventory across multiple equipment types.

Key Features

• A-section V-belt profile for broad sheave and pulley compatibility
• 1/2 inch top width by 81 inch outer circumference matches standard A79 sizing
• Black rubber construction for flexibility and wear resistance
• Suitable for HVAC blowers, fans, compressors, and general industrial drives
• Packaged in quantities of 25 for efficient fleet and shop stocking

Compatibility

Designed as an OEM-style replacement for equipment using standard A-section V-belts with an 81-inch length designation. Fits any sheave or pulley grooved to accept A-section belt profile.

Installation Notes

A licensed HVAC technician or qualified mechanic should disconnect power and lock out the equipment before removing or installing drive belts. Verify sheave alignment and check for sheave wear before installing a new belt. Avoid prying or forcing the belt over sheave flanges, as this can damage belt cords and shorten service life. Belt tension should be set per the equipment manufacturer's specification after installation.
