PennBarry 63017-0 Rubber Washer

The PennBarry 63017-0 Rubber Washer is a flexible mounting component used to provide separation between a fastener and the surrounding surface in HVAC systems. Positioned beneath a bolt, screw, or other hardware, it distributes clamping pressure while reducing direct contact between adjoining parts. The rubber construction also provides a degree of cushioning at the attachment point, which can limit vibration transfer. Installed in fans, blowers, air-handling assemblies, and related equipment, it supports secure fastening without rigid metal-to-metal contact. Within the system, the washer contributes to stable mounting and protects surfaces around the connection.
