Neoprene & Rubber Flat Washer Frequently Asked Questions

Below are answers to some of the most common questions about neoprene rubber washers.

What are neoprene flat washers?
Neoprene flat washers are manufactured from polychloroprene (neoprene) synthetic rubber. As a type of rubber washer, neoprene offers good resistance to oils, weather, ozone, and moderate chemical exposure, and its compressibility makes neoprene rubber washers ideal for sealing, vibration damping, and cushioning applications across a wide temperature range.

What are neoprene rubber washers used for?
Neoprene washers are commonly used as sealing washers under bolt heads and screws in roofing, HVAC, outdoor structures, plumbing, and marine applications. Their rubber compressibility creates a watertight seal when compressed. They are also used as anti-vibration isolators between metal components and as cushioning washers to protect surfaces.

What temperature range can neoprene rubber washers handle?
Neoprene rubber maintains its properties from approximately -40 degrees F to +250 degrees F (-40 degrees C to +121 degrees C), making it suitable for outdoor and moderate-temperature industrial applications. For higher temperatures, EPDM or silicone rubber washers are typically specified instead.

Can you make custom neoprene rubber washers?
Yes. Superior Washer manufactures custom neoprene washers to your OD, ID, and thickness specifications. Contact us via the Quick Quote form or by phone.
