This product is a rubber mounting designed to reduce vibration and noise from air conditioner compressors. It is compatible with compressors ranging from 1 horsepower (HP) to 1.5 HP, as well as those ranging from 2.0 HP to 2.5 HP. The rubber construction helps isolate the compressor's vibrations, leading to quieter and more efficient operation of the air conditioning system. These mountings help extend the lifespan of the compressor by reducing stress and wear caused by excessive vibration.
