4L260 V-belt 4L Section 26 Inch Outside Length

Product Description

The 4L260 is a wrapped, single-rib V-belt in the 4L cross-section, used to transfer rotational power between sheaves in belt-driven HVAC and mechanical equipment. Built with a fabric-covered rubber body and polyester cord reinforcement, it handles the flex and tension demands of blower and fan drive applications. The outside length is 26 inches, top width is 0.5 inches, and thickness is 0.312 inches. The wrapped construction protects the cord package from abrasion and side-wall wear, extending service life in dusty or high-cycle environments. Rated for a temperature range of -22 degrees F to 194 degrees F.

This belt fits standard 4L-section sheave grooves found in residential and light commercial air handlers, furnace blower assemblies, condenser fan drives, and general power transmission equipment. It is a direct replacement for any worn or broken 4L260 belt in the field. HVAC technicians and mechanical service pros typically keep this size on their truck as a common blower belt replacement.

Compatibility

Designed as an OEM-style replacement for any application requiring a 4L-section V-belt with a 26-inch outside length. Fits standard 4L-groove sheaves used in residential and light commercial belt-driven blower and fan assemblies.

Installation Notes

V-belt replacement is typically performed by HVAC technicians or mechanical service professionals. Disconnect and lock out power to the unit before removing the belt guard or accessing the drive assembly. Check sheave alignment and condition before installing the new belt, and set tension per the equipment manufacturer's specification - a properly tensioned belt should deflect slightly under moderate finger pressure at the midspan. Do not use belt dressing compounds on wrapped V-belts, as they can degrade the fabric cover.
