Description

EPDM rubber flat washers designed for panel isolation, sealing, spacing, and vibration control in
electrical enclosures, HVAC equipment, control panels, and industrial maintenance applications.

common 5/16\" bolts and studs used in panel hardware, brackets, and equipment mounting.

Flexible, non-conductive EPDM rubber helps reduce metal-to-metal contact,
surface wear, vibration transfer, and noise in indoor and outdoor environments.
