1/2" ID x 1" OD x 1/16" Rubber Washers NMO Antenna Fleet Marine Trades MRO Pro

Description
These EPDM rubber flat washers are sized for NMO antenna mounts and similar bulkhead
applications where vibration control, sealing, and load distribution are critical. The
1/16" thickness cushions hardware, reduces metal-to-metal contact, and helps protect
painted or coated surfaces on vehicle roofs, marine decks, and equipment panels. EPDM
rubber resists weathering, moisture, and temperature cycling, making these washers
well suited for fleet, marine, and transportation installs. Commonly used by service
technicians and trade professionals for antenna bases, radio mounts, and general MRO
hardware.

These 1/2-inch ID EPDM rubber washers are designed for NMO antenna mounts and other
bulkhead hardware used in fleet, marine, and transportation environments. With a
1-inch (25 mm) outer diameter and 1/16-inch (3 mm) thickness, they distribute load,
reduce vibration, and protect painted or coated surfaces during installation. EPDM
rubber resists weathering and moisture, making these washers suitable for outdoor
vehicle roofs, decks, and equipment panels. Common in radio, GPS, and communications
hardware, they help prevent metal-to-metal contact in professional installs where
durability and consistent fit matter. Designed for MRO teams and technicians working
in inch and metric systems.
