Continental Contitech 20042004 V-belt Section a A79 81.2 in

Product Description

The CONTINENTAL CONTITECH 20042004 is a Section A V-belt designed for power transmission in HVAC, industrial, and mechanical drive applications. Built from Wingprene rubber-impregnated fabric, this belt delivers reliable torque transfer across a wide operating temperature range, from -40 degrees F to 284 degrees F (140 degrees C). With an outside length of 81.2 inches and an internal length of 80.30 inches, it meets the dimensional standard of the A79 belt designation. It is installed by HVAC technicians, mechanical contractors, and industrial service professionals maintaining belt-driven equipment such as blowers, fans, and compressors.

This belt is suited for residential and light commercial HVAC systems as well as general industrial machinery where Section A drive belts are specified. The HY-T Matchmaker profile is engineered for matched-set drive systems, making it appropriate for multi-belt installations where consistent tension and load sharing are critical. Its heat and oil resistance make it a reliable choice in equipment rooms and mechanical spaces where belt degradation from heat soak or lubricant exposure is a common service issue.

Compatibility

Designed as an OEM-style replacement for Section A V-belt drive systems requiring an A79 belt with an 81.2 inch outside length.

Installation Notes

V-belt replacement is performed by HVAC technicians and mechanical service professionals. Always disconnect and lock out power to the equipment before removing belt guards or handling drive components. Use a belt tension gauge when possible to set proper tension — overtensioning shortens bearing life and undertensioning causes slippage and premature belt wear. Inspect sheaves and pulleys for wear, misalignment, or contamination before installing the new belt.
