Product description

The Coats 8112106 40mm Pressure Cup is an essential accessory for professional wheel balancing, designed to fit the popular 40mm shaft systems. This small pressure cup (approximately 4.625 inches in diameter) is used in conjunction with the hub nut to apply even, steady pressure against the face of the wheel during the balancing process. By distributing the clamping force, it ensures that the wheel is seated perfectly square against the backing plate, which is critical for achieving a true and accurate balance. It also acts as a protective interface, preventing the metal hub nut from marring or scratching the surface of alloy wheels. Over time, these cups can become cracked or the rubber lip can wear out, leading to slipping or inaccurate results. Upgrading to a fresh pressure cup restores the precision and wheel-protecting capabilities of your balancer.
