Jason Industrial 3L300 Rubber V-belt 3/8x30

Product Description

The JASON INDUSTRIAL 3L300 is a black rubber V-belt sized 3/8 inch wide by 30 inches in outside circumference, manufactured to the 3L fractional horsepower belt standard. It is used to transmit power between sheaves in light- to medium-duty industrial and HVAC equipment drives. The 3L cross-section is a classic fractional horsepower profile designed for smaller-diameter sheaves and lower horsepower applications. Maintenance technicians, HVAC service pros, and industrial equipment mechanics install this belt as a direct OEM-style replacement or as a service-interval swap on belt-driven equipment.

This belt fits belt-driven applications that call for the 3L cross-section, including fractional horsepower motors found in residential and light commercial HVAC air handlers, blower assemblies, small compressors, fans, and general industrial machinery. The 3L300 designation follows the industry-standard fractional horsepower belt numbering system, where the last three digits indicate a 30-inch outside circumference. It is sold individually and is also available in case quantities of 50 units for shop and fleet stocking.

Installation Notes

Belt replacement should be performed by a qualified HVAC technician or maintenance mechanic. Always de-energize and lock out the equipment before removing the drive guard or handling the belt. Do not use tools to force the belt over sheave flanges; adjust the drive tensioner or motor base to relieve tension before seating the new belt. Verify sheave alignment and proper belt tension after installation to avoid premature wear.
