Description
These EPDM rubber washers are engineered for sealing, spacing, and vibration control in
automotive, HVAC, and light industrial assemblies. The 11/16" inside diameter fits
M16 bolts and oversized studs, while the 1" outer diameter and 1/8" thickness provide
reliable compression without deforming. Manufactured from all-weather EPDM rubber,
they resist ozone, UV, moisture, and temperature swings for dependable indoor or
outdoor performance.
Designed for professional and industrial use, these washers prevent metal-to-metal
contact, reduce noise and vibration, and help block air, dust, and water intrusion in
panels, housings, and enclosures.

These 11/16 inch EPDM rubber washers are designed for sealing and spacing around
mid-size hardware where standard 5/8" or 3/4" washers are too loose or imprecise.
The durable EPDM compound resists ozone, UV, moisture, and temperature extremes,
making them ideal for automotive panels, HVAC access doors, pump covers, and outdoor
equipment enclosures. The 1 inch outer diameter distributes load evenly while the
1/8 inch thickness provides controlled compression that blocks air and water intrusion,
reduces vibration, and prevents metal-to-metal contact in professional repair and
fabrication environments.
