Jason Industrial 3L340 Rubber V-belt 3/8 X 34 in

Product Description

The JASON INDUSTRIAL 3L340 is a rubber V-belt designed for industrial power transmission applications. Measuring 3/8 inches wide and 34 inches in length, this 3L-series belt delivers reliable torque transfer in light-duty to medium-duty drive systems. Built from black rubber compound, it resists heat, oil, and everyday wear in demanding operating environments. Maintenance technicians and industrial service professionals install this belt as a direct replacement in fractional-horsepower drive applications where a standard 3L cross-section is specified.

The 3L340 is suited for use in residential and light commercial equipment, including HVAC blower assemblies, small compressors, agricultural equipment, and general-purpose machinery that call for a 3L-profile V-belt. Its standardized cross-section ensures compatibility with common sheave and pulley configurations found across a wide range of equipment. The belt ships individually and is also available in a package quantity of 50 units, making it practical for stocking in a service fleet or shop inventory.

Compatibility

Designed as a standard 3L-series replacement V-belt for fractional-horsepower drive systems using a 3/8-inch cross-section sheave profile, including common HVAC blower, compressor, and general industrial applications.

Installation Notes

Installation is typically performed by a qualified HVAC technician, industrial mechanic, or maintenance professional. Always de-energize and lock out the equipment before removing the old belt or installing the new one. Verify sheave alignment and inspect pulleys for wear or damage prior to fitting the replacement belt. Do not pry the belt over sheave flanges with sharp tools, as this can damage the belt cord structure and reduce service life.
