Premium Thick Washers for Heavy-Duty Applications
EPDM rubber washers provide exceptional sealing performance combined with the durability needed for heavy duty flat washers applications. These premium washers feature increased thickness compared to standard options, making them ideal for demanding industrial and construction projects. The EPDM material offers superior resistance to weathering, ozone, and temperature extremes while maintaining flexibility under compression. Each item in our Nutty Nuts selection provides excellent diameter consistency and reliable sealing properties that prevent damage to sensitive equipment and surfaces. The rubber construction creates effective barriers against moisture, dust, and contaminants while distributing loads evenly across contact surfaces. Unlike steel washers with black oxide finish, EPDM washers won't corrode or leave marks on finished surfaces. The addition of these specialized washers to your fastener assembly ensures long-lasting performance in applications where traditional metal washers might fail. Professional contractors rely on EPDM rubber washers for their combination of sealing capability, durability, and resistance to environmental factors.
FAQ
EPDM rubber washers typically range from 1/16" to 1/4" thickness depending on the specific item and application requirements. Unlike traditional heavy duty flat washers made from steel, rubber washers can be manufactured in custom thicknesses. The material properties allow for precise thickness control while maintaining diameter specifications and sealing performance characteristics.
EPDM rubber washers are naturally corrosion-resistant as they're made from synthetic rubber material rather than steel. Unlike steel washers that require black oxide finish or other coatings for corrosion protection, EPDM washers won't rust or deteriorate from moisture exposure. This material advantage prevents damage to surrounding components and eliminates corrosion concerns.
Yes, EPDM rubber washers excel in outdoor applications due to their superior weather resistance. The material withstands UV exposure, temperature fluctuations, and moisture without degradation. Unlike steel heavy duty flat washers that may require protective finish treatments, EPDM washers maintain their sealing properties and diameter integrity in harsh outdoor environments without additional protective measures.
USS and SAE specifications apply to steel washers with different diameter and thickness standards. EPDM rubber washers follow different sizing conventions based on sealing requirements rather than USS or SAE specifications. The rubber material allows for custom sizing options, with each item designed for specific sealing applications rather than standardized steel washer dimensions and black oxide finish requirements.
